What key combination cleans up system files on restart?

My system has become slow and I think it has a lot of junk files and such that need to be deleted. I remember there is a key combination that you can use on a restart to delete this files. Anyone remember what that combination is?

Wish it was that easy. The most simple way is to empty your trash.

FreeSpace cost $.99 - FreeSpace shows you how much space is available on all local, connected, and network drives with a single click.
Rule of thumb: You should never let your hard drive get to where you have only 10-15% of space left.

Clean up system files not owned by any package

Hello,
I recently wanted to install nginx and passenger on my laptop for some tests. Passenger requires ruby-rack and it fails to install on my system:

It appears that most of these files are ruby gems (nokogiri, redcloth, etc.). I cannot remember how nor when they ended up here (this is a 2 years old Arch installation).
I already remove all manually installed gems from my system but these files remain. If any of you has an opinion on what would be the best way to clean this, I'd be glad to hear.

I interpreted that as in you used pacman to remove them, my bad. Just to make sure though, you did 'gem uninstall' as root, right? Running it as a normal user just removes the gem files from your user's home directory.
If they're not known by pacman or gem, then you'll need to identify and remove them manually.

What key combination do i use?

To drag a box around a part of the screen and then for it took save the area as a picture?

Apple-shift-4 will give you a crosshair cursor that will let you drag to select a part of the screen. If you press Apple-shift-4 and then press the space bar, you can take a picture of a whole window that will be cropped for you. The files are saved on your Desktop.

Erasing the system files from a previous Windows 7 Home Premium Version.

HP assistant says I have "a copy of an older version of Windows is using significant hard drive space...."
It then suggests I can easily erase the "Windows.old" files with the disc cleanup utility. Not only does the cleanup utility not finde such files, the search bar can locate no such files. Do I just blow it off and "post pone the warning" or is there a solution to shut this warning off by doing something else? Thanks for your help.

Hi:
In order to delete the Windows.old folder (make sure you got any files you wanted from it first if you need to), launch the disk cleanup utility and then hit the Clean up System Files button on the lower left.
It will examine your drive and then show the windows.old folder in the window of the files that can be deleted.
Check all the boxes you want to have the files deleted, and then it should be gone once disk cleanup does its thing.

Edit System File name

I purchased my iMac at a Naval Exchange. It was a display model and it still has a system file named "nex." As I understand, the only way to edit that name is to perform a complete new OS X setup. I'd obviously prefer to simply change the system file name. Help!

I'm not sure what you are calling the "system file"... do you mean the user folder name? If so, it is possible, though not particularly easy or advisable, to change the user name (and thus the user folder name). See:
http://support.apple.com/kb/HT1428?viewlocale=en_US
Since this sounds like a used machine, and could for all you know have something malicious installed by the previous user, you would be wiser to erase the hard drive and reinstall the system from scratch.

Why does the new operating system not delete the moved files from their original location - it seems like an enormous waste of space, time and effort to clean up every file once you've moved it

Why does the new operating system not delete the moved files from their original locations - it seems like an enormous waste of space, time and effort to clean up every file once you've moved it - also, when transferring large amounts of files it becomes a very large problem remembering which files were transferred and which not.

You're going to need to be more specific, as I'm not quite sure I understand what you're talking about.
If you're referring to copying from an external hard drive or flash drive, and you want to actually move files rather than copy them, you can hold down the option key to force it to do a "move" rather than a "copy." This is not new behavior, though... the Mac OS has worked this way as long as I can recall (and I've been using it since 1984).
If you're having a problem with trying to move files from one place to another on a single drive causing them to be copied instead, that is likely because of some permissions issue preventing you from actually being able to move them.

What are the best storage systems to archive inactive (but still used) apps and files?

What are the best storage systems to archive inactive (but still used) apps and files of all types? I already have a Time Casule which I back up on and I'm needing to create more space in my flash drive in my Mac Pro, so I need another external storage system I can use to archive all that I don't currently need. I may still wish to edit and use the files, and I am not very techy and am a broke student... so anything grossly expensive is a no-no for me (between $50 and $200 is idyllic). If you could simply post links of different good/useful hard-drives that I can use, I'd be thankful.
Thank you
p.s. I'm australian, so anything within this country would be great. Or I can deal with somewhere that has cheap shipping.

It's been moved and seconded. Any discussion? Yes:
Buy two external drives. Use one for Time Machine. Be sure this drive is at least twice the capacity of your computer's hard drive. Use the second drive as a bootable clone of your computer's hard drive. Should something happen you can immediately get the computer up and running from the clone until your restore from the Time Machine backup. This is what is called redundancy. Should either backup drive fail, there's another to take its place. Backup redundancy is very important. You can never have too many backups.

What is component used to display system files in FTP

Hello,
I would like to know what is the component that is used to display system files and remote server files in a FTP.
e.g
File Name || File Type || File Size
1.jsp JSP file 1kb
2.java JAVA file 10 kb
Do we need to use JTable to display the headers and a JTree to display the system files? Please help
Thanks

Hi James,
Actually, I am developing where one of its modules is a ftp client.
Mainly, it has 2 panels with JTree's one with the local files and the other, with the remote files.
Have a look to the following links, the are very useful:

What is recommended size of System drive to keep operating system files , paging files and Memory Dump of hyper-v host.

Hi ,
I want to setup hyper-v host with 128 GB RAM , Windows 2012 R2
What is recommended size of System drive to keep operating system files , paging files and Memory Dump?
I tested to using 150 GB , but when the server is crashed, there is no free space to keep memory dump file.
Ramy

Hi Ramy,
For Server 2012R2 the absolute minimum system drive is 32Gb but this assume you have limited RAM or have your Page file located on another drive. It used to be best practice to setup a small page file but MS PFE now suggest leaving windows to manage
the page file size.
Obviously this is not always possible depending on the amount of RAM in the system, but base the system drive around this or offload the Page file to perhaps another drive. On top of this you also need space for the memory dump to be written, potentially
again up to the size of the RAM. Assuming you fire the machine back up after a crash, you need space for the OS, the Page File plus space for the associated dump file.
There is a nice little article here that maybe of assistance: http://social.technet.microsoft.com/wiki/contents/articles/13383.best-practices-for-page-file-and-minimum-drive-size-for-os-partition-on-windows-servers.aspx

How to clean out some files on my macbook air??

So on my mac every time i open it, theres a message that pops up saying my start up disk is full so i go to about mac and then click storage, their it says that my 'movies' and 'others' is taking up a hug amount of space so how can i delete these things??

For information about the Other category in the Storage display, see this support article. If the display seems to be inaccurate, try rebuilding the Spotlight index.
Empty the Trash if you haven't already done so. If you use iPhoto, empty its internal Trash first:
iPhoto ▹ Empty Trash
Do the same in other applications, such as Aperture, that have an internal Trash feature. Then restart the computer. That will temporarily free up some space.
According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation—not the mythical 10%, 15%, or any other percentage. You also need enough space left over to allow for growth of the data. There is little or no performance advantage to having more available space than the minimum Apple recommends. Available storage space that you'll never use is wasted space.
When Time Machine backs up a portable Mac, some of the free space will be used to make local snapshots, which are backup copies of recently deleted files. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown as Backups. The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself. If you followed bad advice to disable local snapshots by running a shell command, you may have ended up with a lot of data in the Other category. Ask for instructions in that case.
See this support article for some simple ways to free up storage space.
You can more effectively use a tool such as OmniDiskSweeper (ODS) or GrandPerspective (GP) to explore the volume and find out what's taking up the space. You can also delete files with it, but don't do that unless you're sure that you know what you're deleting and that all data is safely backed up. That means you have multiple backups, not just one. Note that ODS only works with OS X 10.8 or later. If you're running an older OS version, use GP.
Deleting files inside a photo or iTunes library will corrupt the library. Changes to such a library must be made from within the application that created it. The same goes for Mail files.
Proceed further only if the problem isn't solved by the above steps.
ODS or GP can't see the whole filesystem when you run it just by double-clicking; it only sees files that you have permission to read. To see everything, you have to run it as root.
Back up all data now.
Install the app in the Applications folder as usual. Quit it if it's running.
Triple-click anywhere in the corresponding line of text below on this page to select it, then copy the selected text to the Clipboard by pressing the key combination command-C.
For ODS:
security execute-with-privileges /A*/OmniDiskSweeper.app/*/M*/* 2>&-
For GP:
security execute-with-privileges /A*/GrandPerspective.app/*/M*/* 2>&-
Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad and start typing the name.
Paste into the Terminal window by pressing command-V. You'll be prompted for your login password.
The application window will open behind other open windows. When you scan a volume, the window will eventually show all files in all folders, sorted by size. It may take a few minutes for the app to finish scanning.
I don't recommend that you make a habit of doing this. Don't delete anything as root. If something needs to be deleted, make sure you know what it is and how it got there, and then delete it by other, safer, means. When in doubt, leave it alone or ask for guidance.
When you're done with the app, quit it and also quit Terminal.

Remote not working - system files...?

hi, sorry for the longish post, gonna detail what i've been doing and the other problems i've dealt with, for background. think the only problem left now tho is with the remote.
i coincidentally used my apple remote for the first time yesterday, and it was working fine, with front row and mediacentre.
then later on yesterday, i managed to screw up a lot of my system files using a program called 'monolingual' (it removed the ppc code from the files, leaving only the intel, end result being that rosetta stopped working). ended up reinstalling osx (10.4.6) from the discs that came with the macbook. from what i'd read, i'd been expecting to do an archive & install, but that wasn't offered, it just did an 'upgrade' (tho it was the same version) install of osx over the top.
this fixed rosetta, and other than having to reinstall a couple of programs everything seems to be working normally, except that the remote isn't working at all. the macbook doesn't respond to it at all, the button combination to pair the remote to the mb has no effect, and there aren't even any options in the security preferences relating to the remote.
any ideas how to fix this? any idea which system files are relevant to the remote, that might need refreshing? other suggestions?
thanks,
dave
Macbook Mac OS X (10.4.6)

yep it showed up in the hardware test.. then actually when osx booted back up, it complained about my logitech mouse driver not being installed properly, so i reinstalled that... then rebooted and it complained about some other extension mouse driver, so i reinstalled that... and when it rebooted again, the remote works again!
guess the dodgy drivers were fouling up the usb stuff (yep today i learned that the ir receiver, and the isight, run on usb. today i also restarted my macbook more times than i have in the last few weeks since i got it).
thanks for your help anyway

I may have deleted some system files from my computer due to my antivirus and now my imac won't start. Actually it does, and then there is a blank screeen with the apple logo and it shuts down right away. is tehre a possibility of recovering my files?

Hello
I was having some problems with my Imac, for a while it was slow and often disconneceted from my wifi, while this one worked perfectly (tested with other devices)
I thoug i might have a virus, so i downloaded an antivirus (mac keeper) and started checking.
I also did a scan of my computer using Console or something from the utilities, and then a folder popped witha file I had canceled a while ago. I canceled the file and then my Imac continued to be slow.
i then restarted my Imac, but when it started, the usual grey logo of Apple appeared, and then it shut down suddently.
I tried to reboot it holding the command key and R but nothing, and then i tried holding the shift key and a bar appeared, and at half of the bar it sut itself down again.
I think it is probably a preoblem because I may have cancelled some of the system files from a folder called "private" in the "documents" folder.
Is there any way I can recover some of my files? maybe all of them? I hope so because I have some important files there
Is this a thing I can do myself or do Ineed to go to a MacStore to repair it? Will I need to change HD or just to format it and reinstall? also if there is any way i can recover some of my files that would be great.
Thanks
Ludo
P.S. problems appeared when i installed the Mavericks version.

If MacKeeper corrupted the Recovery partition then even I underestimated its potential for damage. Garbage "cleaning" apps will cause misery but I have not found that the Recovery partition to have been affected by using MacKeeper or anything like it. I doubt that it did so, but I have learned not to underestimate the potential for such things to result in system corruption.
Before concluding your Mac has a hardware failure, try booting OS X Internet Recovery by holding command option r on startup (three fingers). That will force your iMac to bypass the Recovery partition altogether, and convey the ability to create a new one.
An Internet connection will be required (wired or wireless).
At the Mac OS X Utilities screen, select Disk Utility. Select your startup volume (usually named "Macintosh HD") and click the Repair Disk button. Describe any errors it reports in red. If Disk Utility reports "The volume Macintosh HD appears to be OK" in green then you can be reasonably (though not completely) assured your hard disk is in good working order.
Assuming the HD remains usable you can then use Disk Utility to erase it. Reinstall OS X, restore your essential software and other files, and don't reinstall the junk.
