Move location of swap file and safari cache file

Hi,
I have a SSD and want to move the location of my:
System's swap (virtual memory) file
Safrai cache file
To my sd card, to help reduce the wear on my SSD.
Is it possible, if so, how do i do it?
Regards,
Rowland

An SD card is very slow compared to a real SSD. Since these caches are used frequently, the speed impact on your Mac would be terrible.
And besides... From what I read about this issue: the SSD will outlive your MBP by years.

  • Flash Movie has problems in IE and Safari

    Hi, my website's home page works like a charm in FireFox and

  • Adobe Flash Player 9 and Safari Cache

    Just want to let you all know that when the latest Flash Player is installed, the flash cache files are not accessible anymore from the tmp folder in the private folder of the mac HD volume. I had to re-install flash 8 to bring this back. Any clue what's going on here? Is this because the new flash player is re-locating its cache file to somewhere else?
    thanks,
    Robin

    Hi Robin
    I noticed this too - but haven't yet found where they are kept.
    I notice that in the Flash 'settings manager' the amount of used storage shows as very low for each site - it doesn't reflect the sometimes large swfs that have been loaded. Also going back to a page seems to make the entire flash content be reloaded again - which wasn't the case before, as I recall.

  • How to move safari cache file to another location

    How do I do this?  I want to either move it to a RAM drive, or to an SSD drive that is inserted into the Expresscard 34 slot.
    My safari cache is about 6 GB... I hold about 175 tabs open at all times and the constant background refreshing can make things freeze up.
    Or I could turn in off via the Develop Menu...

    Better to never move system files from the location they presently. Safari may not launch at all.
    Best to select: Disable Caches from the Develop menu.

  • DVD for Movie and location for picture files

    In iDVD can I play a movie of some pictures and also use the dvd for a location of the pictures used soe a person can watch the movie or go to a folder from the menu and see the pictures or drag the pictures to their computer?

    Are you referring to the Dvd-Rom section of the dvd? Yes you can add any file you wish to this section but it wont be playable by most set top dvd players. But you can use a computer to drag and drop the data to a different mac or pc.
    Adding files to the DVD-ROM portion of a disc
    You can let viewers copy files directly from your DVD by adding the files to the DVD-ROM portion of the disc. These files are burned onto the DVD and are accessible when the disc is viewed on either a Windows PC or a Macintosh computer, but not a DVD player.
    You can add any kind of file to the disc. For example, if your disc contains a slideshow, you can add the image files to the DVD-ROM portion of the disc so viewers can download them to their own computers and print them. You can also add a file containing your movie production notes and other “extras.”
    To manually add files to the DVD-ROM part of your disc:
    Choose Advanced > Edit DVD-ROM Contents.
    The DVD-ROM Contents window opens.
    Click Add Files, or click New Folder first if you want to create a folder to put the files in.
    Browse to select your files or folders, then click Open to add them to the disc.
    You can also drag files directly to the DVD-ROM Contents window. When you are done, just close the window.
    When you add a file to the DVD-ROM portion of your disc, before you burn the disc the project contains just a reference to the location of the file on your hard disk, not the actual file. So if you delete a file from your computer or move it from its location after adding it to the DVD-ROM contents, you get a “File not found” message when you try to burn your disc. You can either remove these missing files from the DVD-ROM contents or find them on your computer and put them back in the original location so iDVD can access them.
    As you add files to the DVD-ROM contents, be sure to check the DVD Capacity meter in the Project Info window to find out how many gigabytes of disc space are being used. The Capacity meter shows the disc space taken up by the video portion of the disc as well as the DVD-ROM portion.
    NOTE: It is not recommended that you use this feature as a way to create regular system backups on DVD. If you want to create DVD backups of files on your computer’s hard disk, use the Burn Disc feature in the Finder.
    When you add RAW images to a slideshow from iPhoto or from elsewhere on your computer, the files appear as JPEG images in your slideshow. If, in iDVD preferences, you choose to add photos from the slideshow to the DVD-ROM portion of the disc (so that viewers can download them to their computers), the RAW files are added, not JPEGs.
    Hope this helps but if not just come on back.

  • Where are the actual Aperture files located? Only in the application? I am transitioning to Lightroom and would like to only move some of the files. Advice appreciated. Also anyone know how to transfer in with edits?

    Where are the actual Aperture files located? Only in the application? I am transitioning to Lightroom and would like to only move some of the files. Advice appreciated. Also anyone know how to transfer in with edits? Using iMac, OS X, most recent Aperture and Lightroom 5.7 with plugin for Aperture.

    Define "the Aperture files".
    Read this concise guide.
    The files you imported into an Aperture Library can be exported (at any time, and repeatedly) using the command "File ▹ Export ▹ Originals".  Your Originals are never altered.  What went in is what comes out.
    Adjustments and changes to the metadata that you made since creating an Image in Aperture by importing a file are saved to a text file.  This file is combined, on-the-fly, with the Original to create the Image that you see in Aperture.  There is no file saved to disk that is the full-size Image.  Thumbnails are saved, and Previews are saved.  These are JPG files, almost always smaller than the Original.  They are not substitutes for the Image for the use you have.
    When you need a file of an Image to use in another program, you export the Image from Aperture.  "Export" means "Make me a file of this Image according to these file specs I'm providing".  The way to get files of your adjusted Images is simple:  create them by exporting.  Specify "Original size", and use a loss-less image-file format (e.g. TIFF 16-bit) if you want to retain as much visual information as possible.
    Search the Web for information about transitioning from Aperture to Lightroom.  Note that I say "transitioning".  You cannot move a database from one format to another without significant changes, and likely some loss of information.  Adobe provides a tool and some instructions.  I strongly recommend working out the process step-by-step, and then proceeding with first a few Images, then a bushel-ful, and stopping to use the first few, the the bushel-ful, before committing your entire collection to the process.
    As always, never use any computer file without having a back-up.
    We have seen mixed reports here of the success of the LR tool that creates a LR database from your Aperture database.
    If you want to carefully define the process, and test and refine it, use the excellent process-development, analysis, and execution program inShort.
    Sadly, there is not and can never be a good, thorough re-positioning of the digital assets in your Aperture Library to become digital assets in a LR database.  Just as a metaphor for any user contemplating transitioning to another digital asset manager:  that would be like digging up a house in one country, planting it in a hole in another country, and expecting to be able to use the toilet and the sinks, turn on the lights, cook dinner, and sleep soundly.

  • How to move huge HD video files between external hard drives and defrag ext drive?

    I have huge high definition video files on a 2TB external hard drive (and its clone).  The external hard drive is maxed out.  I would like to move many of the video files to a new 3TB external hard drive (G-drive, and a clone) and leave a sub-group of video files (1+ TB) on the original external hard drive (and its clone).  
    I am copying files from original external drive ("ext drive A") to new external drive ("ext drive B") via Carbon Copy Cloner (selecting iMovie event by event that I want to transfer). Just a note: I do not know how to partition or make bootable drives, I see suggestions with these steps in them.
    My questions:
    1.)  I assume this transfer of files will create extreme fragmentation on drive A.  Should I reformat/re-initialize ext drive A after moving the files I want?  If so, how best to do this?  Do I use "Erase" within Disk Utilities?  Do I need to do anything else before transfering files back onto ext drive A from its clone?
    2.) Do I also need to defrag if I reformat ext drive A? Do I defrag instead of or in addition to reformating?  If so, how to do this? I've read on these forums so many warnings and heard too many stories of this going awry.  Which 3rd party software to use? 
    Thank you in advance for any suggestions, tips, advice.  This whole process makes me SO nervous.

    Here is a very good writeup on de-fragging in the OS environment that I borrowed
    From Klaus1:
    Defragmentation in OS X:
    http://support.apple.com/kb/HT1375  which states:
    You probably won't need to optimize at all if you use Mac OS X. Here's why:
    Hard disk capacity is generally much greater now than a few years ago. With more free space available, the file system doesn't need to fill up every "nook and cranny." Mac OS Extended formatting (HFS Plus) avoids reusing space from deleted files as much as possible, to avoid prematurely filling small areas of recently-freed space.
    Mac OS X 10.2 and later includes delayed allocation for Mac OS X Extended-formatted volumes. This allows a number of small allocations to be combined into a single large allocation in one area of the disk.
    Fragmentation was often caused by continually appending data to existing files, especially with resource forks. With faster hard drives and better caching, as well as the new application packaging format, many applications simply rewrite the entire file each time. Mac OS X 10.3 onwards can also automatically defragment such slow-growing files. This process is sometimes known as "Hot-File-Adaptive-Clustering."
    Aggressive read-ahead and write-behind caching means that minor fragmentation has less effect on perceived system performance.
    Whilst 'defragging' OS X is rarely necessary, Rod Hagen has produced this excellent analysis of the situation which is worth reading:
    Most users, as long as they leave plenty of free space available , and don't work regularly in situations where very large files are written and rewritten, are unlikely to notice the effects of fragmentation on either their files or on the drives free space much.
    As the drive fills the situations becomes progressively more significant, however.
    Some people will tell you that "OSX defrags your files anyway". This is only partly true. It defrags files that are less than 20 MB in size. It doesn't defrag larger files and it doesn't defrag the free space on the drive. In fact the method it uses to defrag the smaller files actually increases the extent of free space fragmentation. Eventually, in fact, once the largest free space fragments are down to less than 20 MB (not uncommon on a drive that has , say only 10% free space left) it begins to give up trying to defrag altogether. Despite this, the system copes very well without defragging as long as you have plenty of room.
    Again, this doesn't matter much when the drive is half empty or better, but it does when it gets fullish, and it does especially when it gets fullish if you are regularly dealing with large files , like video or serious audio stuff.
    If you look through this discussion board you will see quite a few complaints from people who find that their drive gets "slow". Often you will see that say that "still have 10 or 20 gigs free" or the like. On modern large drives by this stage they are usually in fact down to the point where the internal defragmentation routines can no longer operate , where their drives are working like navvies to keep up with finding space for any larger files, together with room for "scratch files", virtual memory, directories etc etc etc. Such users are operating in a zone where they put a lot more stress on their drives as a result, often start complaining of increased "heat", etc etc. Most obviously, though, the computer slows down to a speed not much better than that of molasses. Eventually the directories and other related files may collapse altogether and they find themselves with a next to unrecoverable disk problems.
    By this time, of course, defragging itself has already become just about impossible. The amount of work required to shift the data into contiguous blocks is immense, puts additional stress on the drive, takes forever, etc etc. The extent of fragmentation of free space at this stage can be simply staggering, and any large files you subsequently write are likely to be divided into many , many tens of thousands of fragments scattered across the drive. Not only this, but things like the "extents files", which record where all the bits are located, will begin to grow astronomically as a result, putting even more pressure on your already stressed drive, and increasing the risk of major failures.
    Ultimately this adds up to a situation where you can identify maybe three "phases" of mac life when it comes to the need for defragmentation.
    In the "first phase" (with your drive less than half full), it doesn't matter much at all - probably not enough to even make it worth doing.
    In the "second phase" (between , say 50% free space and 20% free space remaining) it becomes progressively more useful, but , depending on the use you put your computer to you won't see much difference at the higher levels of free space unless you are serious video buff who needs to keep their drives operating as efficiently and fast as possible - chances are they will be using fast external drives over FW800 or eSata to compliment their internal HD anyway.
    At the lower end though (when boot drives get down around the 20% mark on , say, a 250 or 500 Gig drive) I certainly begin to see an impact on performance and stability when working with large image files, mapping software, and the like, especially those which rely on the use of their own "scratch" files, and especially in situations where I am using multiple applications simultaneously, if I haven't defragmented the drive for a while. For me, defragmenting (I use iDefrag too - it is the only third party app I trust for this after seeing people with problems using TechToolPro and Drive Genius for such things) gives a substantial performance boost in this sort of situation and improves operational stability. I usually try to get in first these days and defrag more regularly (about once a month) when the drive is down to 30% free space or lower.
    Between 20% and 10% free space is a bit of a "doubtful region". Most people will still be able to defrag successfully in this sort of area, though the time taken and the risks associated increase as the free space declines. My own advice to people in this sort of area is that they start choosing their new , bigger HD, because they obviously are going to need one very soon, and try to "clear the decks" so that they maintain that 20% free buffer until they do. Defragging regularly (perhaps even once a fortnight) will actually benefit them substantially during this "phase", but maybe doing so will lull them into a false sense of security and keep them from seriously recognising that they need to be moving to a bigger HD!
    Once they are down to that last ten per cent of free space, though, they are treading on glass. Free space fragmentation at least will already be a serious issue on their computers but if they try to defrag with a utility without first making substantially more space available then they may find it runs into problems or is so slow that they give up half way through and do the damage themselves, especially if they are using one of the less "forgiving" utilities!
    In this case I think the best way to proceed is to clone the internal drive to a larger external with SuperDuper, replace the internal drive with a larger one and then clone back to it. No-one down to the last ten percent of their drive really has enough room to move. Defragging it will certainly speed it up, and may even save them from major problems briefly, but we all know that before too long they are going to be in the same situation again. Better to deal with the matter properly and replace the drive with something more akin to their real needs once this point is reached. Heck, big HDs are as cheap as chips these days! It is mad to struggle on with sluggish performance, instability, and the possible risk of losing the lot, in such a situation.

  • Changing swap file location on tray-loader iMacs

    This is not a question, but something I discovered that makes my old tray-loader iMac (the oldest iMac models) run Mac OS X much better.
    As you may know, these oldest iMacs have an 8GB size limit on the boot volume. The largest stock drive on these iMacs was 6GB. That means if your upgraded hard drive is larger than 8GB, it must be partition so that the first partition is under 8GB (7.78GB on my iMac), and it must be the boot partition where the OS is installed (whether it's Mac OS X or 9).
    In my case, I have a roomy 120GB hard drive (I believe the useable limit on these iMacs is 128GB). The first partition is just under 8GB, the second partition is the rest of the space, about 104GB. I have used every trick out there to move files (such as the iTunes music folder and most of my user/documents files) off to the second partition, to make free space on the boot partition as large as possible. So I have 3.5GB free on my 8GB boot partition. This is about 40% of the volume's total space so it seems pretty good, until you realize that most recent Macs have much more than the TOTAL 8GB I have, as free space on the boot volume. Mac OS X was just not designed to work well with small boot volumes...
    Mac OS X uses the free space on the boot volume for its virtual memory "swap file." Considering these old iMacs max out at 512MB of RAM, virtual memory is being used quite a bit. But since space on the boot volume is very limited, low RAM and lack of free space can lead to performance issues. Here's what I observed. When I initially started up my iMac, I had about 3.5GB of free space. Over time, as I used more and more apps, that free space would diminish until I had only about 600MB remaining (as reported by a Finder window). At the same time, I noticed performance getting bogged down and more "chugging" sounds coming from the hard-working hard drive.
    I've known about changing location of the swap file, but never tried it until recently. During the Mac OS X boot process, the Mac sets the location of the swap file. By default, the swap file resides on the boot volume (I believe most other Unix-based systems use a dedicated "swap partition" for the swap file). Since most recent Macs have large drives set up as one partition (and there is plenty of free space), and since many users have upgraded their RAM (and virtual memory is not as critical), swap file location is usually not an issue, and there is certainly no need to change the swap file location. However, on my iMac with an 8GB limit on the boot volume and 512MB of RAM, it made a noticeable difference.
    I found one set of procedures on the web that was much better than the others I found for changing the location of the swap file.
    http://www.math.columbia.edu/~bayer/OSX/swapfile/
    On this page, there are two choices for Panther users. I used the one that works for both Panther and Tiger, because it appeared to me to be more straightforward. The author intentionally keeps the instructions somewhat technical to discourage users who are not technically inclined. I don't consider myself to be too "geeky," but I can follow instructions and type a few commands in Terminal.
    After I changed the swap file location to a large mostly empty volume, I noticed much better performance when I have many large apps open at the same time. Performance no longer degrades over time, and the free space on my boot volume remains a constant 3.6GB.
    The reason for this post is to share this information. Some users of these old iMacs may be noticing the same issues I had. This is a possible solution. However, if everything is OK with your set up, there is no reason to change the swap file location. If you try it, be sure to take the usual data backup precautions.
    If anyone else has experience with changing swap file location, please post your comments here.

    Problem has been solved:

  • Swap file size and tracking down the culprit

    I have a new MacBook Air running Mountain Lion and I've been having problems with swap files. While the swap seems to default to 64 MB when I start, it will quickly grow to 2 GB and then the machine seems to create new files after every time I wake the machine from sleep, but the older swap files are left around until I restart. At 2 GB or so per file, this means I'm forced to restart simply to recover lost disk space. I have 8 GB of real memory, but even with 5 or 6 GB free, the swap file still grows.
    Since the problem occurs even when I'm not using my computer for much else I've narrowed the four main culprits to HP printer software, Dropbox, Crashplan, and Lytro. I completely uninstalled Lytro and all its support files this morning and uninstalled the HP printer drivers. I downloaded the most recent installer from HP and did a minimal install so that the HP Print Monitor is not part of the installation.
    This still leaves Crashplan, which requires Java if you are going to run the main app and then Dropbox, which has a menu component as well as background processes.
    Of course, the problem could be some other service or application that has a memory leak, but I don't know how to go about diagnosing the problem. Do either Crashplan or Dropbox have known memory leak issues?
    I have iCloud turned on, Time Machine is off, and Sharing is off. I use a combination of Safari, Firefox, and Google Chrome for browsing, but typically only have Chrome open; but I guess there is a possibility that a plug-in is causing problems.

    No, I see nothing recent in that directory (haven't used it in a while anyway). I suppose it was a simple matter of a bloated pacman cache.
    I think you may have misunderstood. If you unmount /mnt/backups you should see no files at all when you list the directory. Any files which are there will be masked when the partition is mounted.
    You're right. I misunderstood you, and having finally tried your suggestion I find that you were absolutely right!  Thank you!!  This was so perplexing me how I could not account for such a significant amount of space on such a meager partition, and this buys me a lot more time to strategize what to do with this file system
    I unmounted /mnt/backups and found that 1.7 GB of files were still left over, which I was able to remove.  Now my file sizes add up, except only ~ 0.5G (of a 7.8G file system), which I guess is probably the 5% that ext3 is "reserving for root"?
    Anyway, I like to idea of sparing some space for being able to log into root in case I fill up my system again (it certainly came in handy this time), but how much can I reasonably reduce that amount to?

    Hi Jo,
    If I'm interpreting this correctly, the Word file downloads correctly, but when you open it in Pages, the link(s) which your instructor has embedded in the Word file are not correctly translated into Pages.
    If the link shows the actual address, you should be able to copy that and paste it into the location bar in Safari, press return, and get to the website that way.
    An alternate route might be to download one of the open source Office applications, OpenOffice.org, LibreOffice, or NeoOffice. These are written to more closely emulate the behaviours of MS Word than Pages, and may provide better support for links embedded in Word files.

  • Swap file locations

    Hi,
    A few questions regarding an upgrade to ecc 6.0.
    What is the recomended swap files locations - on the server's disks or on the storage disks (connected to the server of course).
    and what is the recomended swap files quantity if i have 8 GB of ram and what is the recomended splited files quantity?
    Regards,
    Moshe

    This depends on your operating system, whether your´re on 32- or 64-bit.
    Usually it´s best to have the swap space on a separate disk isolated from OS, database and application.

  • MacBook Air and Safari movie download problems

    I bought a new MacBook Air in August 2013 (OS 10.8.5). After migrating all my files from my iMac I have encountered problems with downloading movies that are playing in Safari (v 6.0.5). On my iMac (OS 10.6.8) and Safari (v 5.1.10) I could go under "Window", select "Activity" and see the files associated with the movie. I could select the movie that was playing, copy the url & then past it into "Downloads" (also under the "Window"). The movie would then download to my preferred folder & I could then view it on my iMac. I can't find the "Activity" or the "Downloads" options under the "Window". How do I get the movies to download now?
    Thanks,

  • VAR and Swap Files - Taking up 3 gigs of space!

    My 60 gig HD has been getting close to its size limit so I ran DiskSweeper to see if there were some unneeded files etc. that I could throw away. I discovered that the VAR folder was using 1.95 gigs and in the VM folder, the swap files were taking up about 1 gig...
    I guess these are essential system files and can’t be deleted or reduced in size, or can they?
    Thanks in advance!

    To clear the swap file(s) restart your computer. I've never had more than two swap files, but then I have enough RAM for what I do. If your system keeps creating large swap files then it is a sign you need more RAM. If you can't get more, you'll need to limit the number of RAM hungry programs you have running at the same time. Because of the things that get dynamically created as you work, such as swap files and temp files, you should have a minimum of 10% of your drive free, and 15 would be safer. If I were you I would make sure I always had 10GBs free. You might look into getting an external drive, and move some of your files over to it. For instance, you can move your iTunes music library to another drive--I've done that because my startup drive is also a "mere" 60GBs.

    Hi Sam,
    I understand where you are about being your own IT department, it can be overwhelming ...
    What drives to buy depends an awful lot on how you will use them, what your budget is, and your preferences.
    In the case of your DP Powermac, for online storage used primarily for editing, I would add one or more internal drives first. Look for drives that are at least 7200rpm and have at least an 8MB cache. 10,000rpm/16MB cache is even better, but more expensive. Seagate Barracudas have always been good choices.
    For backup purposes, I'd pick some good external FireWire drives; you can also use these for online editing, lots of people do. Your Mac has both FW400 and FW800 ports - either kind is fine but if you get drives that support both, you would want to connect them to the FW800 port for the added performance.
    In my experience, the Lacie d2 Extreme drives have been very very good. In fact I have 3 of them daisy-chained off my iMac G5 right now and they work flawlessly with FCE. Weibetech and Granite Digital drives are further upscale in performance and price. RAID configurations would be even further upscale. Do stay away from consumer level hard drives, however ... the Western Digital MyBook series & no-name drives come to mind ...
    Don't use a FireWire hub for your external drives, it's just asking for trouble.
    ps. And thanks for your nice comment about me. I'm happy to help, as are other folk in the forum.
