Oh oh! you want to be very very very careful before deleting any files from LW's Library window. Deletions are permanent.

The only way you might possiby retrieve them is thru a file retrieval utility such as norton utilities. There are some others. If you're really dead-serious about retreiving the files you've deleted, you should stop doing anything else on that hdd before you attempt to use a file retrieval utiltiy. Otherwise any new files will write over the skeletons of the previous files that were stored there thus reducing/cancelling any chance of retrieving such files.
