Hi.
I have 2 cd's from galaxie software. They are both the same books but one is newer then the other. When I installed L4 I used the "scan" command to let L4 copy those books from one of those discs.
The problem now is, that I scanned the old disc. How do I get the disc with the newer books into L4? Do I just do a scan command again and it will overwrite the old files or can I just copy the newer books into the L4 resources folder (replacing the old ones)?
