Curious, how big would your playlist/amount-of-files have to be before this layered FIDs to appear faster?

Like has been said before, this greatly depends on the number of files in your fids dir. On my player, this number was approaching 15.000 per drive.

Changing this to the new structure made a huge difference in responsiveness to shell commands. Especially "rwm" took seconds instead of minutes, and rsync started transferring much sooner. I was so enthusiastic that I made the new scheme the default for mp3tofid.

One important thing is to create new fids directories after converting, as the old fids directories stay big, even if you empty them; ie something like

mkdir fids.new

mv fids/* fids.new

rmdir fids

mv fids.new fids

Even better would be to start with freshly mke2fs'ed filesystems.
