USB Reader/Writer - KN7000

I've saved some Technics files into a folder on the SD card. The USB reader/writer identifies these files (including the .ACT file). I then hoped to copy some of these files (several at a time) onto another folder or another SD card.
After copying these files with the USB reader/writer to a new folder - it identifies these files.
BUT when I put the SD card back in the KN7000 the original folder identifies the tunes, but the new folder is shown as empty
Anyone (Alec) any ideas???

don't use explorer on card operations. Use the supplied utilities to preserve the display information. Use backup and restore, then copy in the screen for this job.

Hallo,
So with the supplied software you can tranfer an entire directory on the harddisk off the computer (with maximum 20 songs) to the Sd card ?
Thanks,
Alain

I already answered on technote, Alain.
