Reclaim drive space by deleting iPod/iPhone firmware System
Here's a quick and painless way to regain some drive space. When iTunes downloads a new firmware for your iPod or iPhone, the older ones do not get deleted. Since they are quite big (for the iPhone, at least -- about 250MB each for my 2G iPhone), you can easily free up more than 1GB of drive space by deleting the older ones (which you usually won't need anyway).

The firmware files are located here:

~/Library/iTunes/iPhone Software Updates
~/Library/iTunes/iPod Software Updates

Just check the file names for the version numbers, and delete the older ones. If you're unsure, you can delete all of them, as iTunes will then re-download the newest one only when it's needed (i.e. a restore of an iPhone).

No great hint, but still nice to know.

I disagree. It is indeed a great hint! Recovered 600 MB which is no small change for us Rev1 MBA users! Many thanks!

I have a MBP and replaced my HD with a 250 GB model, but still I'm trying to not waste space. :-) Glad you liked the hint.

Deleting the files has a side benefit, as well.

As a matter of course, I delete them all. Having gotten an iPod Touch stuck in a "restore" endless loop, and finding that part of the problem causing the loop was the software's inability to properly recognize already-downloaded updaters, I've found that it's far simpler (although a little more time-consuming) to have iTunes go through the process of downloading and using the latest firm/software updates when restoring a Touch.

Especially useful for those of us who have had several different models of iPod over time an all sorts of update files filling up that folder.

Just discoverd this for myself recently and saved myself about 800MB or so of space.

You should also be able to remove the iPod Cache folde rinside iPhoto Libraries.

Default one is at:
~/Pictures/iPhoto Library/iPod Photo Cache/

Mine is at 350Mb right now... and since it's a cache, it will be re-generated If Needed!

'Show Content' on iPhoto Library to gain access (at least with iLife '09)

It's the little things (or not so little, at 1 GB). Thanks!

Do you know if it is safe to delete all of the old application versions in ~/Music/iTunes/Mobile Applications? I have 1.5gb in there, sometimes as many as nine versions. If the most recent is needed, it will be a manual process as they are labeled app 1.ipa, app 1.2.ipa, app 2.ipa etc.

I did that once and all was well. On one app version I wasn't sure which was the newest, so I deleted them both and the right one was synced back from my iPhone.

Reclaim drive space by deleting iPod/iPhone firmware
Authored by: picto on Feb 18, '09 04:31:38AM

Can these files be re-used? ie applied to a different machine as a file copy rather than a download?

My daughter is mostly off-line (basically restricted online status) and I take other updates over on a stick, but these updates are not available as downloads from Apple - they require iTunes being online and the iPhone connected.

Also they are big files

So it would be useful to just copy the file to allow her to update her iPhone to 2.2.1

Any experts know?

I see no reason why it shouldn't work. Just make szre to copy the correct firmware file to the correct location on her Mac and do it while iTunes is not running.
