Reorder folders on FAT32 drive

Question

My car can read MP3 files from a FAT32 flash drive. I have a folder for each artist on the drive, then MP3 files in those folders.

However the car does not read the folders alphabetically, but by the order they were added to the drive. I can use DriveSort to sort the drive after I add a new artist. Could this "sorting" be done from the command line, perhaps using touch?

Answer 1

Depending on what OS you are using there are command line utilities such as:

• FatSort

And touch won't help you with sort since all you will be able to do with it is manipulate the timestamps on the file or directories.

Answer 2

I think Linux's FAT32 driver fills directory entries in the order they're created, so all you have to do is add the files in the order they're wanted. If you want to insert a file in the middle, move everything to a temporary directory and then back. If you want alphabetical order, it's easily done from the shell, since wildcards expand to a list sorted in alphabetical order.

mkdir tmp
mv * tmp      # ignore the complaint about not being able to move tmp as a subdirectory of itself
mv tmp/* .
rmdir tmp

If you want to do this to the contents of every directory on the drive:

cd /media/sdcard
mkdir tmp
find . -path ./tmp -prune -o -type d -exec sh -c '
  mv "$0"/* tmp
  mv tmp/* "$0"
' {} \;
