Preserve artist/title across backup/restore

[jmr]

I just got a bigger memory card, so did a backup/restore to move the songs to the new card.

When managing the old card, I could see the artist/title because it was in the file name (as well as the metadata of the files I originally imported).

For the new card, all file names are just replaced with numbers, so it's hard to see what's what.

It would be great if the artist/title were somehow carried over, either in the filename or metadata. I looked and it appears that WAV supports metadata.

With a little bit of further investigation, it looks like the metadata would have been preserved if the card had been written with this version of the software, but it was done with the old (was it Adobe air?) version.
