Weren’t you surprised the first time you read that warning? Worse still you know you only have a few small photos and not a single video in your iPod touch. Yet your iPod touch is already running out of disk space. WTF?

To keep a long story short, Apple split the iPod touch’s flash drive into two partitions. The first partition named “iPhone Root FileSystem” (yes, iPhone… even though that’s an iPod) is about 300mb in size. It is, as the name implies, where Apple installed iPod touch’s mini “OS X” in. The second partition, “Root’s Home”, stores all your media and misc files. Its size is the capacity of your iPod touch (8GB or 16GB) minus the 300MB allocated to the first partition.

The low disk space warning is on the first partition as you add more and more apps to your jailbroken iPod touch. To overcome this problem, we can move the /Applications folder to the second partition. Doing so frees up about 40MB. But that’s not the best part. After moving, you can theoretically install every iPod touch apps available to be brim and still never experience low disk space again.

Let’s move it. There are two methods:

Hard:

Easy:

  1. Use the BossTool by Big Boss. You can find it in the Installer, under the “Utilities” category. The Installer source for Big Boss’ apps is as follows:
    http://www.sleepers.net/~iphone/repo.xml
    Check your typing. The URL is cAsE sensitive. “/~iphone/” and “.xml” must be in small letters only.
  2. Launch BossTool and tap on “Free Disk Space”.
  3. Follow its instructions to move your Apps and Wallpapers (we don’t have Ringtones in the iPod). If you’re not comfortable about moving your Apps, then move just the Wallpaper. This should buy you some time until you run out of space again in future.
  4. Unless you like the other functions of BossTool, you can uninstall it after it has done its job. You’ll only need it again the next time you Recover your iPod touch.

    Hi Rupert: After using BigBoss to “move” my apps and wallpapers to the Root’sHome partition,I went back in with AFPd to have a look at the changes. I found that the Applications folder was still in the FileSystem partition but that somehow I had almost 50MB free (as compared to 9Mb before the move). I expected to find just an alias for the Apps folder. However, Get Info says it is real and has 31.7 Mb of stuff in it. Where did the free space come from?

    Roksob, that’s the magic of Symbolic Link. Perhaps you’re more familiar with Mac OS X’s alias? Symbolic Link is Unix’s own alias. The old Application folder you see is a fake. It’s really just a file that *points* to the new Application folder. The alias-ed folder takes up just a few kilobytes of disk space. So even though you see two Application folders, only one is real and taking up disk space.

    It’s precisely because it looks and act like the real thing we can use this trick to fool the iPod into thinking everything isn’t changed even though we have actually moved the Application folder to another partition. Haha.

    So when I put on applications, do I put them in the original folder (the small one), or do I put them to where I transferred all my files?

    reicc, you’ll put them in the new one. After that, they will show up in the old one as well. Read my comment to Roksob dated Dec 31 to find out why it is so.

    This sounds great! But I can’t seem to find BigBoss in the Installer! What should I do? I think I have the same problem as pablo.

    Alex, I’m sure you added the source to BigBoss’ repository. But I’m guessing you typed it in wrongly. The URL is cAsE sensitive, and your iPod probably changed it to “/~iPhone”. Delete the bad entry, and add it again, carefully.

    A tip for everybody: Sources are listed in the Installer with their names. If a Source is named “Untitled”, it’s a bad one with an invalid URL. You’ll want to delete that source.

    Alex, tap on “123″ and you’ll see “#+=” on top of it. It’s there in, above comma. :P

    Hi Rupert. I went to this website, but I got this page with junk info with “Untitled”. Do you have any suggestions?

    Hi Anne

    Do you mean this website?

    http://www.sleepers.net/~iphone/repo.xml

    You don’t surf to it. You add the url address to your iPod touch’s Installer, as a new “Source”. The Source option is to the right of “Uninstall”.
