Hello Alec,
I have 3 SD cards off 64 Mb.
If I want to use the entire capacity off the sd card I have to put 20 sequenser songs on one directory.
Normally I put one disk that contains 10 songs on a diferent directory. If I would do this I would be able to put 99 disks on my SD card.
If I copy 2 disks (20 songs) to one directory it would be possible to put 20 * 99 songs on the Sd card.
I hope I'm wright because I am reorganizing all the files from the backup off my hdsx6.

Thanks again,
Alain
