Is it safe to delete everything in my Caches folder?

This folder tends to get very large, with thousands of files in it. I already have an AppleScript to automatically do my cron jobs and I was thinking of adding a command to delete the *entire contents* of my Caches folder every day as well.
Is it safe to do this?

But some of the third party applications may ask your permission when you want to open files associated to those applications.
Why would deleting caches make them do that?

  • Safe to delete content from the Temp folder under AppData?

    Hi everyone,
    Is it safe to delete the contents from the Temp folder (C:\Windows\ServiceProfiles\LocalService\AppData\Local\Temp) in the SharePoint 2013 web front end servers?
    For some reason I see around 30 GB of temp files. Came across
    this blog post but in my case ULS logs are still being generated in the D drive. Not sure how those Temp files are being created. Application servers seem to be fine. 
    Tried - 
    changing the ULS log path from D to C and back to D drive (as per the above blog post... no luck)
    tried restarting the SP tracing service
    Any suggestions would be appreciated!

  • In iPhoto '11, is it safe to delete aliases in the masters folder?

    I'm running the latest update of iPhoto '11.
    I'm trying to do some house cleaning and I'm discovering many duplicates of photos because I used to have iphoto copy pictures into the library.
    So, I'm getting rid of duplicates, and I keep coming across these folders which have aliases to the original picture (not in the library).
    I've noticed that some of these aliases are pointing to pictures that are no longer there (i.e. I deleted them a long time ago).  So I was wondering if it's safe to delete the aliases.
    I've noticed that any photos added in '11 dont actually have aliases.  Only the photos added in prior versions.
    On a similar note, if it's not safe to delete the aliases, then if I did delete them, would they be recreated somehow? (like, if i rebuild the library database by pressing "command" and "option" on iphoto launch....or something).
    Just curious so I can continue my house cleaning.
    Thanks in advance.

    It's impossible to say whether it's safe to delete those aliases or not. What you're doing is simply not supported.
    There are two possible uses for aliases in an 11 Library. One is linking up the old Library to the new structure. The other is to track referenced files. So, good luck with that.
    I'm sure you've thought this decision through but for the benefit of others who may be thinking of this:
    A Referenced Library is when iPhoto is NOT copying the files into the iPhoto Library when importing. The files are then stored where ever you put them and not in the Library package. In this scenario you are responsible for the File Management.
    This is an attractive option for some users at face value, but it contains a significant number of issues that you might want to consider before making the decision to run a Referenced Library
    How to do it:
    iPhoto -> Preferences -> Advanced and uncheck the box at 'Copy items to the iPhoto Library'
    Now when you import iPhoto makes an alias in the Library Package that points to the stored file. Note: iPhoto still creates a thumbnail of the image and it makes a Preview of edited photos inside the Library Package.
    Issues?
    1. You are responsible for file management. That's more work:
    You must first move the files from your camera to the storage location before importing.
    If you want to delete files then you must first trash them from iPhoto and then afterwards find them in your storage and trash them.
    Thereafter, you cannot move the files on early versions of iPhoto at all, on iPhoto 08 and later you may move them on the same Volume or Disk. If you move them to a new volume or disk the aliases my break. If they are on an different volume and you move them the aliases will break.
    You cannot rename the files.
    Migrating: moving to a new machine, moving the files to another disk are all a lot more complex.
    2. You gain no extra functionality from running a Referenced Library. Nothing. This is just storage. You still manage the files via iPhoto. You edit them with iPhoto or via iPhoto's External Editor setting, otherwise you're changes will not be available in iPhoto. You don't save  byte of storage space.
    3.  If you have the Library on one volume and the photos on another you if anything changes in the path to a file (Like if you upgrade your machine, move the files on the NAS or on to another one?) then the alias will break, and you'll have to repair it manually. For every photo in the Library. One at a time.
    Why do you want to run a Referenced Library?
    Because my photos won't fit on my HD?
    You can run a Managed library from an external disk. Make sure the drive is formatted Mac OS Extended (Journaled)
    1. Quit iPhoto
    2. Copy the iPhoto Library from your Pictures Folder to the External Disk.
    3. Hold down the option (or alt) key while launching iPhoto. From the resulting menu select 'Choose Library' and navigate to the new location. From that point on this will be the default location of your library.
    4. Test the library and when you're sure all is well, trash the one on your internal HD to free up space.
    You're worried about accessing the files?
    There are many, many ways to access your files in iPhoto:   You can use any Open / Attach / Browse dialogue. On the left there's a Media heading, your pics can be accessed there. Command-Click for selecting multiple pics.
    (Note the above illustration is not a Finder Window. It's the dialogue you get when you go File -> Open)
    You can access the Library from the New Message Window in Mail:
    There's a similar option in Outlook and many, many other apps.  If you use Apple's Mail, Entourage, AOL or Eudora you can email from within iPhoto.
    If you use a Cocoa-based Browser such as Safari, you can drag the pics from the iPhoto Window to the Attach window in the browser.
    If you want to access the files with iPhoto not running:
    For users of 10.6 and later:  You can download a free Services component from MacOSXAutomation  which will give you access to the iPhoto Library from your Services Menu.
    Using the Services Preference Pane you can even create a keyboard shortcut for it.
    For Users of 10.4 and 10.5 Create a Media Browser using Automator (takes about 10 seconds) or use this free utility Karelia iMedia Browser
    Other options include:
    Drag and Drop: Drag a photo from the iPhoto Window to the desktop, there iPhoto will make a full-sized copy of the pic.
    File -> Export: Select the files in the iPhoto Window and go File -> Export. The dialogue will give you various options, including altering the format, naming the files and changing the size. Again, producing a copy.
    Show File:  a. On iPhoto 09 and earlier:  Right- (or Control-) Click on a pic and in the resulting dialogue choose 'Show File'. A Finder window will pop open with the file already selected.    3.b.
    b: On iPhoto 11 and later: Select one of the affected photos in the iPhoto Window and go File -> Reveal in Finder -> Original. A Finder window will pop open with the file already selected.
    Regards

  • Is it safe to delete ALL caches and/or receipts?

    is it safe to delete ALL files and folders under "user/library/caches"? I was surprised to see how big it has gotten. and is it safe to delete "macintosh hd/library/caches"?
    how about receipts located in "user/library/receipts" and/or in "macintosh hd/library/receipts"?
    how about unders "user/library/preferences"?
    thanks for the help.

    Regarding receipts, as already provided check these links.

    http://docs.info.apple.com/article.html?artnum=25768
    Regarding the preference files at Home > Library > Preferences, these are the preference files for your applications and the Finder, etc. so if deleted for a particular application, this will require resetting your preferred preference settings for the application. If there is a preference file available for an application you have deleted, the application's preference file can also be deleted but these preference files take up very little hard drive space and cause no adverse effects if not deleted when the associated application is deleted.
    Are you trying to free up hard drive space? If so, check this link.

  • HT201269 My old iPhone (I no longer have) is still an active device on my iCloud backup list.  Is it safe to delete it?  Can I be sure everything on the cloud for that old device has been transferred?

    My old iPhone (I no longer have) is still an active device on my iCloud backup list.  Is it safe to delete it?  Can I be sure everything on the cloud for that old device has been transferred?

    The only way the backup from ilcoud has been transferred to a new apple device would be if YOU restored the new device with the mentioned backup. There is nothing 'safe' about you deleting this backup if in fact you have not restored the new device with this backup.
    Good luck Friend.

  • HT204053 I am trying to set up my icloud account. It is telling me my account is not verified to check my email for verification. It is telling me to check my email at my Apple account? Everything is greyed out on the screen. Is it safe to delete this acc

    Hi.I am having difficulty setting up my icloud account on my iphone4. It's telling me Account not verified and to check my email at my apple account.The screen is greyed out and i cannot switch on any of the apps.Also icloud backup is off.  Is it safe to delete this account? will it erase everything on my phone??

    Make sure you are checking the email address you used to set up your iCloud account.  Check the spam/junk folder as well as the inbox.  If it isn't there, go to https://appleid.apple.com, click Manage your Apple ID, sign in, click on Name, ID and Email addresses on the left, then to the right click Resend under your Primary Email Address to resend the verification email.

    Please help me, Im at my wits end and about to stomp on my blackberry. The last couple weeks everytime I push a button it gets the timer up. its faster to take the battery out at this point than wait for the timer. drives me nuts!
    So I searched for fixes and all anyone says is to make sure all apps "close", Well I deleted all my apps and closed all the ones I cant delete.
    Still happens!
    I held down alt and pressed lglg and deleted the event log,
    Still Happens!
    Deleted everything saved on the internet from cookies to passwords.
    Still Happens!
    I reset my phone by taking out the battery for 5 min a few times a day
    Still Happens!
    What is going on here? Theres no way Im buying another blackberry if I can't fix this.

    Sometimes things just fail. OS Corruption. Hardware failure. Etc. etc. etc. All are possible. We can't truly diagnose here...all we can do is conduct various processes to hopefully deduce to a most likely root cause. If you want a true and fast diagnosis, you must take your BB to a qualified technician who can examine it in their hands. We can only do so much at an internet distance.

    Yes, there is a specific command for that. But it does not reload your OS, so if the problem happens to be within your OS itself, conducting that won't help.
    Tell me how you'd like to proceed. Your choices are to continue with the deductive diagnostic processes we can give you versus seeking in-person support.

  • Is it safe to delete iTunes media that is no longer available in the iTunes Store?

    There is a support document that states it is OK to delete content locally so long as the content is available in the cloud depending on your geographic location.  As I'm in the US all media types are available.  From the document:
    You can delete items that you bought from the iTunes Store, App Store, iBooks Store, or Mac App Store from your iOS device, Mac, or PC. Because Apple TV (2nd and 3rd generation) plays content from the cloud, you don't need to delete items from your Apple TV.
    Before you delete an item, make sure you can download it again. If you can't or need to pay to download it again, back up the item before you delete it.
    What I am still not clear on is if it is also safe to delete content that is no longer available in the iTunes store?  Will it still be available for previous purchases?
    I prefer the quality and off-line availability of iTunes media over Google Play but I've had issues recovering deleted media in iTunes in the past and so have less anxiety about the security of my purchases on Google Play versus iTunes.  Can someone confirm if items no longer available for sale in iTunes are or are not still available via the cloud?

    Thanks for the reply although I'm not too happy to hear it.  What's awesome about the cloud is no longer having to keep up with any physical media.  The promise of that is realized with everything else (my work, music, books) besides movies and TV.
    I wonder how Google Play will handle movies/tv that becomes unavailable?  Google Play does allow you to download media in some circumstances (on Android and iOS) but is generally intended  for streaming.  Maybe relying on a physical copy as I do with iTunes should make me more comfortable with it and not less. 
    I will come back to mark your reply as the solution as it becomes clear there is not a contrary position.  Thank you.

  • Installing clean Win 8.1 on X1- is it safe to delete all partitions first?

    I have created a Windows 8.1 installation USB drive using the Microsoft tool and am going to install it on my X1 (gen 2), but wanted to check if it's safe to delete all 6 partitions on the drive using the installation and let the Windows installer recreate the required Microsoft reserved partition?
    The first 1000MB partition is the one I am concerned about- should I leave that alone? I can't fine any confirmed details about what it's used for.
    I have created a Lenovo recovery drive as well in case it goes wrong.
    Thanks!

    If everything is on your computer, as it should be, then you are safe.
    Not sure what you want.
    Your iphone simply mirros the selected content of your computer.  If all of your content is on your computer, then it will be on your iphone.

  • Startup disk is full when I already deleted everything?

    For a while I've been getting pop ups saying my startup disk is full and so I deleted mostly everything. To this day I still get the pop ups when I swear there is literally nothing on my macbook. I checked how much space I actually have and I have just 1.17 gb/59.81 gb... I have no idea how this could possibly happen when I have deleted everything.
    There is 0 pictures, 0 movies, 0 downloads and 0 music because I have literally deleted everything. How do I only have 1.17 gb left? My trash is also empty too. Apparently "Other" is taking up 41 gb on my macbook... What is this? I have no idea what is taking up all the space on my macbook when I don't have anything except the things I really need.
    Someone help me... I need actual space on my laptop...

    For information about the Other category in the Storage display, see this support article. If the Storage 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 an iPhoto or Aperture library will corrupt the library. Any changes to a photo 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.
    If you have more than one user account, make sure you're logged in as an administrator. The administrator account is the one that was created automatically when you first set up the computer.
    Install the app you downloaded 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:
    sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper
    sudo /Applications/GrandPerspective.app/Contents/MacOS/GrandPerspective
    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. Click Utilities, then Terminal in the icon grid.
    Paste into the Terminal window by pressing command-V. You'll be prompted for your login password, which won't be displayed when you type it. Type carefully and then press return. You may get a one-time warning to be careful. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator. Ignore any other messages that appear in the Terminal window.
    The application window will open, eventually showing 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.

  • Safe to delete file from Time Machine hard drive?

    Is it safe to delete a file from an external hard drive that's being used for Time Machine backups? The file is not a backup -- it's a .dmg from the manufacturer of the hard drive. Other than that one file, I don't use the drive for anything other than Time Machine.
    I'm just concerned because I don't want deleting the file to affect Time Machine in any way.
    Thank you.

    I have done it without issue.

  • What happens if I click "delete backup" in order to delete the iCloud backups from my sisters phone off my device. Will it delete everything on her phone?

    So a while ago when I got my phone I started a new Apple ID account/ iCloud.. Then when my sister got a new iphone I gave her my id to use too. In settings-general-usage it says that my storage is almost full. I then click on manage storage and it shows my phone and my sisters phone and how many gb or whatever. Also it says "last backup failed" and other stuff that's Irrelevant. Now when I click on my sisters phone I have an option to "delete backup" MY QUESTION is if I click the delete backup button will it just delete the iCloud backup off my phone OR will it totally delete everything involving the backup off my sisters phone forever??? Please help! Thank you so much!!!!!

    Deleting a backup deletes the backup only from the iCloud storage, not anything on the iPhone.
    The iPhone's iCloud backup will be updated at some point - automatically when the iPhone is connected to an available wi-fi network while connected to a power source unless the iCloud backup is turned off on the iPhone.

  • If all the photos from my iPhone 4s Camera Roll show up in iPhoto under Library- Photos, is it safe to delete them from the iPhone and not risk losing them?

    I am getting messages about being out of space on my phone for taking any more photos. I am scared to delete anything with all the photo stream and syncing that happens cause I don't want the photo to delete in many places at the same time.
    So, 1) when is it safe to delete from the iPhone? 2) I feel like I have multiple copies of photos stored between the phone, Photos Library in iPhoto and all my albums in iPhoto. Is there a best practice document on how to manage your photos for space savings? 
    I've looked, but can't find my answer clearly in the forums.

    IF you have successfully imported your pictures to your Mac http://support.apple.com/kb/HT4083  then it's safe to delete it from your phone.
    If you want the pics back on your phone, just sync them back using itunes http://support.apple.com/kb/HT4236
