#15 restore tree

[TomDeMan]

It would be faster to have a restore tree instead of a list
of files. This way only the top nodes should be displayed
and those could be expanded when the user presses the
+ in front of it.
I would suggest using the berkeley DB to sort the
filenames into nodes. It's a free very fast open source
DB which I used before, I could help you implement it if
you like...
