iTunes 4.8 fiddles with file names on iPods
Scott Knaster, of Hacking iPod + iTunes, reports that with the recent release of iTunes 4.8 the file system of the ipod has been slightly changed. Pre 4.8 the file names on your iPod were the same as the file names on your Mac. When you navigated the hidden folders on the iPod it was a snap to figure out which file was which.
Now all the file names are changed during the syncing process with your iPod. The new file names consist of four, seemingly, random characters in an effort to make the database on the iPod a little faster.
This shouldn't impact many users, but it is good to know.
