Which of these folders contents can I delete

I want to free up some space on the hard drive, and I know this is where all the memory is being taken up at. Which folders contents can I delete, that will not effect playback and exporting of my sequence in a project?
[IMG]http://i194.photobucket.com/albums/z161/Honda16Kelly/Picture1-1.png[/IMG]

within these folders you should find that you have subfolders for each of your current projects
if you find that there are folders for projects which are already completed, signed off, mastered to tape and/or achived, then you can safely delete those particular projects subfolder
warning: be careful that you are not deleting content from one old project which you are actually reusing in a new and current project

What are all these folders

This has been bugging me for some time. On my main harddrive I keep seeing all these weird folders at the root level appearing.

What's in 'em? Can you view any of them with textedit? Also what's their file size?

I've tried a lot of Apps and Themes and deleted them from my phone. But they're still in "My Stuff" in Ovi Store, which is annoying.
How can I delete them?

IPad won't turn off so I can reset it because my emails are locked. I receive emails but can't access them, can't delete, can't send.

My iPad won't turn off so I can reset it. My emails are locked but I receive emails as the number of emails increases. I can't access these emails, I can't delete the one email showing, and I can't send an email. The screen is locked.

Try a reset:
1. Hold the Sleep and Home button down (together)
2. For about 10 seconds
3. Until you see the Apple logo (very important)
4. Ignore the red slider

I have duplicate pictures in "my catalog" that I believe come from two Adobe folders found under "my pictures/adobe/ one is Revel and the other is Photoshop express which preceded revel. Can I delete those two folder without causing a problem with my catalog?

Thanks for the links, Limnos.
If you are willing to continue helping, here's what I found.
Just to clarify the two iTunes folders I am refering to are:
username-->Music-->iTunes
HD-->iTunes
I am presuming each location has a full set of files as outlined in the above links?
Not all the files are in both locations. Most are.
- The Itunes folder in my home folder does not have itunes library.xml.
- The Itunes folder in my home folder has a subfolder called Mobile Applications (username-->Music-->iTunes--> Mobile application). The Itunes folder at the HD level also has a Mobile Application folder but it is a subfolder of Itunes Media folder (HD-->iTunes--> iTunes Media-->Mobile applications) and has no files in it.
- I do not have an iTunes Media in the iTunes folder in my home folder.
- also the Itunes media folder (HD-->iTunes--> iTunes Media) has subfolders by type (books, movies, itunes u, music etc...) but the iTunes Media-->Music also has some of the same subfolders ( iTunes Media-->Music-->books, iTunes Media-->Music-->Movies, iTunes Media-->Music-->iTunes U). Is this normal repetition?
You say:
/itunes/itunes media/ music
but it is important to note what comes before all that.
There is nothing as far as I can tell before that first forward slash. Since the only iTunes Media folder I have is in the iTunes folder that resides at the HD level (HD-->iTunes--> iTunes Media folder) not the iTunes folder in my home folder (username-->Music-->iTunes) , I assume that's the one that holds the music.
Keep iTunes media folder organized and Copy files to iTunes Media folder when adding to library are both checked on
Does that give more clarity into my problem?

How do the User and Shared Folders relate to the main drive? Can we delete?

I'm curious how the User and Shared folders relate to the main hard drive and if there is duplicate files in these folders and the main hard drive. Some software programs I have seemed to have loaded content/info into these folders and I'm wondering why they put files in there instead of just the regular main hard drive pathing. These 2 folders are more confusing than anything. I can see that might be of use to a family and each family member wants to keep files in a personal file, but when I'm the only one using my computer, it seems like I should have the option to remove these folders completely, but I don't because I feel like I would be deleting some important files that I wasn't aware were in these folders.
Another thing is, when I click on User folders (at least I think it's the User and not Shared folder), it brings up my name and 'Shared' in 2 seperate subfolders. Is anything in these folders duplicates of what's on my main hard drive? Is there anything significant about these folders if I'm the only user on my computer?
I would nice to get rid of clutter and to eliminate options for software to install things by deleting these folders and not have home/user/shared folders. Is that possible?

Yeah, I'm really low on space, so I'm going about a bunch of different consolidating options. But I mainly posted my main question to help me understand what 'stuff' is in the User and Shared folders and whether or not they act like an Alias, in order to help me make an informed decision what is best for my needs.
They are not aliases; it is a hierarchy, and there is intentional duplication at different levels. This is a feature.
First thing is that Users and Shared are at different levels. Users is at the top level, but Shared is one level inside Users, at the same level as any other user account you have created.
Therefore, if you delete the Users folder, you delete all user accounts, which means you delete all personal data. OS X probably won't even let you delete the Users folder unless you start up from a different hard drive, because you can't delete your user account while you are running in it.
Now, more about the hierarchy. The intentional duplication is so that documents and software can exist for individual users or all users. For example, there are multiple Applications folders:
Hard Drive\Applications - applications any user can see, installed at the system level
Hard Drive\Users\username1\Applications = applications only that user can see
Hard Drive\Users\username2\Applications = applications only that user can see
In the same way, there are multiple Preferences, Cookies, Application Support, etc. folders at different levels, for the same reasons.
If you do not know what you are doing and you delete one of these folders that "looks like a duplicate" you could cripple some essential part of your system or your account. That is why people are telling you not to do this.
The Shared folder is there because if you are in one user account you are prevented from seeing the files inside other user accounts. (Because you don't want other accounts to be able to see your personal data.) If you want to share files with others in your house using the same Mac, that's a problem. But the Shared folder solves this. if you want some files to be accessible to all users, like some photos or music, just put them in the Shared folder and now anyone with an account on that computer can see those shared files.
The reason shared files are not simply stored at the top level is because everything above the Users folder is supposed to be reserved for the system. User-specific are supposed to stay in the Users folder. That is why they put the Shared folder in there.
If you are not using the Shared folder and are just eyeing it because you want to free up some disk space, well, it probably won't help to delete it. Because if you are not using the Shared folder, it is probably not taking up much space, even though you see stuff in there. And if there is stuff in there taking up space, first figure out if someone put it there for a reason before you delete it.

Iphotos Package Contents: What are all these folders for? Is it too large to back up in the cloud?

Dear experts, I am quite a newbie when it comes to understanding the Mac filing system, as I originally came from the PC world. There's lots of things I dont understand in the iMac file viewer and how to organise and backup my photos is an important issue for me.
I know that if I want to look at the original photo files on my iMac, I can right-click on users/myname/pictures and select "Show Package Contents".
Question 1 - What are all these folders for?
Please can someone explain what is the difference between all the folders I see? Some of them seem to be exact duplicates of the others e.g. Masters, Modified and Originals all seem to have the same content. So here is a list of folders that I see. What is in them?, or what is their purpose?
Data
Data.noindex
Modified
Originals
Apple TV Photo Cache
Attachments
Auto Import
Backup
Caches
Contents
Database
iLifeShared
iPod Photo Cache
Masters
Previews
ProjectCache
Thumbnails
Question 2 - Which photo folder should I back-up?
If I want to keep a physical backup of my photos, which of the above folders should I copy to an external hard drive? (I use Get Backup to automatically copy all important new or changed files to an external drive)
Question 3 - Using the cloud: What is the best way to backup my large photo library in the cloud safely?
I would like to have some kind of safe backup in the cloud for my photos. However the size of the iphoto library is huge at 165GB. Even the Masters folder is huge. It is 130GB. Is it possible to back up files of this size in the cloud? I have a couple of services called photo streaming and Dropbox, but they don't seem to be able to handle this kind of size. Photo streaming only works with 1000 photos (as far as I can tell), and my Dropbox probably has a limit too. I guess it's about 5GB. I am already using about 3GB of my Dropbox space for other files. I would consider both paid and free solutions.
Many thanks to all the experts for your help!

know that if I want to look at the original photo files on my iMac, I can right-click on users/myname/pictures and select "Show Package Contents".
Don't do that. That's like opening the hood of your car and trying to figure out what all the different bits and peices are and which you can yank out and dispose of. Simply, there are no user-serviceable parts in here.
So, your Question 2:
You back up the iPhoto Library as a single unit.
Most Simple Back Up:
Drag the iPhoto Library from your Pictures Folder to another Disk. This will make a copy on that disk.
Slightly more complex: Use an app that will do incremental back ups. This is a very good way to work. The first time you run the back up the app will make a complete copy of the Library. Thereafter it will update the back up with the changes you have made. That makes subsequent back ups much faster. Many of these apps also have scheduling capabilities: So set it up and it will do the back up automatically.
Example of such apps: Chronosync - but there are many others. Search on MacUpdate or the App Store
Your question 3:
There is no good back up to the Cloud. There are a couple of reasons for this. One is that the datasets are so large and the cloud services shapre their download speeds. This means restoring can take days to complete. Then, and this is the big problem, the iPhoto Library needs to sit on a disk formatted Mac OS Extended (Journaled). Bluntly, no servers online are formatted appropriately, and if the Library is written to - by an incremental back up, for instance - there is a very high likelihood that the library will be corrupted.
Your Question 1:
The Library you're describing there sounds like one that has been updated a few times. Not everything you list there is a folder. Some will be aliases.
The Data folders hold thumbnails.
The Masters and Originals folders hold the files as imported from the camera
The Previews hold the versions of the edited photos that are accessed via the Sharing mechanism.
I think if you look losely that you'll notice that one of the Data folders and one of either the Masters or the Originals folders is actually an alias.
Everything else is a database or cache file of some form. All are required for iPhoto to work.
As an FYI:

Can't Delete "StartupManager" or "InputManager" folders after sys reinstall

I had to do a archive and reinstall awhile back. Everything went fine, and I recently tried to delete the "Previous Systems" folder. Everything in the folder was deleted except for 2 locked folders named StartupManagers and InputManagers, which were locked. I attempted to unlock them, but whenever I tried to give Read & Write permissions to myself, it would just switch back to "No Access" on its own. This prevented me from unlocking the folders in order to delete them.
I tried a number of solutions from this forum and others using the command line and single-user mode, and I was finally able to remove the checkmark next to "Locked" in the Info windows for the folders. However, I still don't have Write privileges to either folder, and when I go through the steps of changing permissions, it just switches right back to "No Access."
The thing is, I actually ran into this problem some time ago, and after much googling, I did figure it out, but I can't find the information this time.
This is my last ditch effort before doing a Erase & Reinstall. Any help or information from anyone else who has run into this would be most appreciated.

See if this helps: Fix No Access Permissions on HD or this:
To fix this:
1. Launch Terminal, which resides in the Macintosh HD > Applications > Utilities folder.
2. At the Terminal prompt, type the following command:
sudo chmod a+rwx "/Volumes/partition_name"
where: partition_name is the name of the affected partition.
3. Press Return.
4. Type your Admin password when prompted, then press Return.
5. At the Terminal prompt, type exit and press Return.
6. Quit (Command-Q) Terminal.
7. Relaunch Finder: Press and hold the Option key, click and hold mouse button 1 on the Finder icon in the Dock, select "Relaunch" from the Finder icon's contextual menu.
You should then see the volume, or be able to use Disk Utility to Unmount it, then Mount it and see it.
Reset the permissions for Group and Other for the partition as desired. Do not change the permissions for Owner.
If you want a volume / partition unmounted at startup, see:
• this tip Mac OS X Hints, or...
• this tip on the OSX86 Project forums.
Good luck!

I have both an iMovie.app and iMovie 9.09.app on my Macbook Air. Can I delete one of these apps without losing iMovie? I need to free up space on my Macbook Air as I don't have any space left. I've ordered an external drive in order to move photos and video there to free up space. In the meantime I have to make some room for incoming emails and to open programs. I've already deleted some documents.

My facebook app went dark and had the word "waiting" below it and I can not delete so I downloaded a new facebook app which is ok but the old app is still there but now the word "waiting" is gone and still cannot delete.

My facebook app went dark and had the word "waiting" below it and I can not delete so I downloaded a new facebook app which is ok but the old app is still there but now the word "waiting" is gone and still cannot delete.

This is my boilerplate respone for the "waiting apps" problem. Give these suggestions a try in order.
1. Tap the "waiting" icon and see if you can pause it. If it does pause, then tap it again and see if it will resume. If that works, repeat the same steps for each "waiting" icon.
2. Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.
3. Make sure that you do not have a stalled download in iTunes - if you have a download in there that did not finish, complete that one first.
4. If that doesn't work - sign out of your account, restart the iPad and then sign in again.
Settings>iTunes & App Store>Apple ID. Tap your ID and sign out. Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
Go back to Settings>iTunes & App Store>Sign in and then try to update again. Tap one waiting icon only if necessary to start the download stream.
5. You can also try deleting the waiting icons - tap and hold down on an icon until it wiggles - the tap the X on the icon to delete it. Then try to download again. Apps may also be able to be deleted in Settings>General>Usage>Storage if you cannot get the X to pop up on the icon.
6. You can try resetting all settings. Settings>General>Reset>Reset All Settings. You will have to enter all of your device settings again.... All of the settings in the settings app will have to be re-entered.
7. If all else fails, download the updates or the apps in iTunes on your computer and then sync the content to your iPad.

Can I delete the files/folders in 'Apple Computer\MobileSync\Backup'?

Hi!
I have just tried to backup and update my iphone to iOS 5.1. The backup seems to have worked but when it came to restoring the iphone, I think the hard disk ran out of space and so it failed. I saw this and so I freed up around 3Gb of disk space and I tried it again. It again failed. Again I noticed that there was no space left on the hard disk. I assumed that to continue the restore it probably won't need that much more space (as it had already done most of the work) so I freed up a few more Gb.
Again it failed. When it fails, itunes leaves the partially restored elements on my hard disk meaning that my 'Apple Computer' folder is now 28Gb!! I cannot afford to delete anything else from the hard disk. I am using a PC by the way. I have noticed that in the folder 'Apple Computer\MobileSync\Backup' has 5 folders in it which is the same amount that I tried to restore the iphone (before the last restore attempt there were 4 folders). These folders amount to 20Gb. From this I am assuming that the actual backup that I made is infact in 'Apple Computer\iTunes\Mobile Backups'.
Can I delete the folders in 'MobileSync\Backup'? This would free up 20Gb of disk space giving me enough to properly restore (in theory!).
Thanks for your time!!
Nick

your advice worked for me and saved me what ever evil lurked behind my thought to just delete the backup and get back my very lmited space on my 250GB Mackbook Pro using daisydisk pro https://itunes.apple.com/us/app/daisydisk/id411643860?mt=12
Why DaisyDisk?
DaisyDisk remains the tool of choice for film makers (including companies like Pixar), digital artists, IT professionals and hundreds of thousands of Mac users worldwide when it comes to disk space management. Constantly improving since its initial introduction, the app easily blows away competition in terms of speed, efficiency and user experience.

Possible to set it so you can't delete a specific folder and contents...

Hello.
I'm wondering if anyone knows a way I can set a folder so that a user can't delete the folder (and thus, the contents by deleting that folder). But, at the same time, I want them to be able to manage the items within the folder (ie. can delete sub-folders, can add sub-folders, etc.).
Basically, right now each computer in the studio has a "jobs" folder. This folder gets backed up (via the network via Retrospect) each night and users can add/delete jobs as they want. But, they can also accidentally delete this folder by having selected the main folder itself and hitting command-delete, or by moving it to the trash. I know it's not "likely", but it is possible and I'm hoping to prevent it.
I thought I could lock the folder so you can't delete it, but this seemed to also make it so the user can't add files either.
So, wondering if anyone has any suggestions (native or 3rd-party)?
Thanks,
Kristin.

If I create a temporary directory owned by me and grant read/write/execute permission to me, my group and others, I can add and delete items inside it but I cannot remove the directory itself while working as another user. If I gave ownership of the directory to root, I would also be unable to remove it.
While this is not secure - certainly admin users could delete the directory itself if they wanted to - it should prevent accidental removal of the sort you describe. Check it works on 10.5, though.

I have an external hard drive that was formatted by a PC and has files and directories etc. I want to format it and use it on my IMAC for backup but I can't seem to write to it nor can I delete current content. How do I initialize it for use with the MAC?

I have an external hard drive that was formatted by a PC and has files and directories copied to it etc. I want to use it on my IMAC for backup. I see it on my my IMAC . I can open files etc. But I can't seem to write to it nor can I delete current content. I don't care if I lose current content. How do I initialize it for use with the MAC?

You can't write to it because it's formatted as NTFS which OS X will read but not write to. If you want to continue using the drive with both a PC and OS X you will need to download and install NTFS-3G so you can then write to it from your Mac. You can get NTFS-3G at:
http://www.macupdate.com/app/mac/24481/ntfs-3g
If you want to use the drive exclusively with your Mac then move the data off it and reformat it in Disk Utility (Applications - Utilities - Disk Utilities) as Mac OS Extended (Journaled.)

How can I delete all these photos?

I just bought an iPad mini Retina and I noticed these photos,which are not mine. How can I delete them? Is this iCloud problem?

Another way to remove all the photos (and to generally make sure you have a fresh iPad for your OWN use) is to completely restore the device to factory settings. My suspicion though is that if the person you bought it from didn't know to remove their photos, they certainly didn't know about iCloud: Activation Lock. When you restore the device it will ask for the Apple ID and password used to originally activate it. Without that information, the iPad is little more than an expensive brick.
If the device belonged to the person you bought it from - and wasn't lost or stolen and then resold to you for example - this shouldn't be a problem. The original owner can follow the instructions in that link to remove the device from their iCloud profile. Once that's done, you can activate the iPad under your own Apple ID.

How can I delete a dir which has sub-dir's ?

Dear list,
Can some one send me a link or send me a code example of how to delete all the sub- directories in a specified directory. My dir has sub-directories which contain files!
If I use the java.io package I must loop all the sub- directories, and java.io.File.delete() wont delete a dir when it contains files, so I will have to go into each sub-dir and delete the files before deleting the sub-dir. This is going to be a lot of code, and YES ! I am a little lazy!
Is there a java package, with a method, where I can just delete a dir, which just deletes it and ALL its contents ?
regards
BB

    // Delete an empty directory
    boolean success = (new File("directoryName")).delete();
    if (!success) {
        // Deletion failed
    }If the directory is not empty, it is necessary to first recursively delete all files and subdirectories in the directory. Here is a method that will delete a non-empty directory.     // Deletes all files and subdirectories under dir.
    // Returns true if all deletions were successful.
    // If a deletion fails, the method stops attempting to delete and returns false.
    public static boolean deleteDir(File dir) {
        if (dir.isDirectory()) {
            String[] children = dir.list();
            for (int i=0; i<children.length; i++) {
                boolean success = deleteDir(new File(dir, children));
if (!success) {
return false;
// The directory is now empty so delete it
return dir.delete();
