What is the "Other" folder on my mac? and how do i reduce its size?

i have an "other" folder on my macbook pro which is 54gb in size? and i have no idea what is in this file or how to delete it? Can anyone help?
i do not understand why it is so big, it has grown by 3 gb today alone. I also have smaller "other" folders on my ipad and iphone but they are only 1gb.
Does anyone know what these folders actually are?? and more importantly how to delete them?

What's the 'other' part in my storage and how do I get rid of it?

A big part of the storage of my iPod Touch 4th Generation is occupied with 'other', it's about 7 GB. What is this and how do I get rid of it?

What is the Other on my iPhone and How to Remove It
An "other" that large usually indicates that the "other" includes corrupted files.
First try:
"First you go settings/general/usage/music/then left swipe over music and press delete and you would think it deletes your music but it doesn't instead it deletes your other but make sure your ipod is connected to a computer while doing this"
as recommended by:

Next, usually restoring from backup eliminated the corrupted files. However, sometimes restoring to factory settings/new iPod is required.

What is the "other" section on my ipod and how do i remove it

hi, im not the most ipod literate user in the world, but i have heaps of storage space being used in the section other. what is in there and how do i take it off?

Hi, welcome to Apple Discussions.
"Other" is the measure of used space on the iPod not taken up by Audio, Video & Photos. This includes the iPod's library and artwork plus any files you may have copied to your iPod in disk mode. The overhead for the library & artwork data is typically 1-2% of the size of the media, e.g. for 100Gb of Audio & Video expect to have around 1.5Gb of "Other". This information is needed for the iPod's operation and cannot be removed.
If you have significantly larger amounts of "Other", not related to files you've intentionally placed on the iPod, then these are probably disconnected copies of your media files or iPod libraries left over from failed sync operations. The only way to recover the space is to do a full restore.

If you have copies of all your media in your iTunes library this isn't a problem, but if you've been manually managing the content then you might need to try to recover the files from it first. See this post by Zevoneer on transferring files from the iPod to your computer. Some of the tools rely on the iPod having a healthy library however the manual method mentioned towards the end of the post should work regardless.
Note restoring should clear all files from the iPod's drive however sometimes it doesn't actually seem to work. Options include manually deleting all visible & hidden files & folders via Explorer/Finder or formatting the drive.
When repopulating the drive you may find breaking the process up into smaller stages makes it less likely to fail.
Break up large transfers
In iTunes select the menu item File... New Smart Playlist. Change the first drop-down box to Playlist, the next to is and the next to Music or whatever playlist holds the bulk of the content you want on your device. Tick against Limit to, type in say 10, then change the drop-down to GB, and set the last drop-down to artist. When you click OK you can enter a name for the playlist, e.g. Transfer. Now sync this playlist to your iPod rather than your entire library. When the sync is complete modify the rule (File... Edit playlist) to increase the size by your chosen amount, then sync and repeat. You can experiment with different size increments, if it doesn't work just choose something a bit smaller until it works each time. Before long you should have all your music on your iPod. Once that's done you can move on to other media such as podcasts, videos, photos, playlists etc.

/var is a hidden folder, so you mustn't remove the folder.
The only solution is to reinstall OS X. If you have OS X Lion or Mountain Lion, use OS X Recovery > http://support.apple.com/kb/HT4718
Hold Command and R keys while your MacBook is starting and reinstall OS X. You won't lose anything. If you have a backup, you can restore it after starting in OS X Recovery instead of reinstalling Mac OS X, so you will save a lot of time

Reinstall OS X.
Reinstall Snow Leopard without erasing the drive
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install Mac OS X 10.6.8 Update Combo v1.1.

Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.

Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

What is the other category on my mac book pro for hard drive space on how do I improve on it

What is the "other" category on my mac book pro for hard drive space? I found out that it is taking a whole lot of my computer's space...how do I find what it is and optimize it?

If you need to remove files for space see The XLab FAQs and read the FAQ on freeing space on your hard drive. Also see Freeing space on your Mac OS X startup disk.
Under no circumstances should you try deleting files outside of your Home folder.

It doesn't matter when you installed antivirus software; if you have it on your computer it will frequently block access from applications to sites it does not know about. A sync does not require access to a site not on your computer; an upgrade clearly does. So if you have never jailbroken any device you do not need to be concerned about your hosts file, but you DO need to temporarily disable your antivirus during the update process.
The hosts file is an operating system file on all computers that overrides DNS lookup. In order to jailbreak or hack an iDevice the programs that do it need to redirect iTunes so it does not go to the Apple activation server, but instead goes to the hacking program for activation instructions. It does this by adding a record to the hosts file that bypasses the DNS lookup for gs.apple.com. But you don't have to be concerned about this.

What is including in the other section of my memory and how do I manage it?

I'm running out of memory and I can't seem to find out what is in the section labeled as other when I connect the Ipad to itunes. Can anyone help?

that other folder is files sync'd from your pc but are not readable by the device. so try this but understand its a complete data loss and your backup will have the "other folder" so must be set up as new. as far a permanent fix buy a mac computer and dont sync with windows
recovery mode
open itunes on computer
plug cable into computer not phone
turn phone off
hold home button and plug cable into phone. do not release home button until an itunes graphic appears on device.
look to computer should have message about recovery mode click ok and restore
Peace, Clyde
