Thanks Jim.  I guess it was the Adobe tech rep that threw me for a loop.  You'd think they would know what the program is supposed to do.

Since I can see no reason to keep files for deleted and "returned" books, I wonder how one goes about making suggestions to Adobe to include the deletion of files added to the PC when the books are deleted from the library.

Unfortunately, I have no idea why nothing is deleted from the drive by Adobe.  I do know that the answer given to the other poster was incorrect when Adobe claimed the files would be deleted "in a few days."

That my very well be true, but it still doesn't negate the fact that the Adobe Tech. Rep. said that the files would be deleted "in a few days."

I don't have a problem with deleting the files myself if I choose to, but I think the original question was why didn't Adobe do it automatically when items were "returned" or "deleted" and the answer was not related to position of it being a "safety measure."

I think by now we all know the files stay and it is up to us to delete.

I've never borrowed the same book again in EPUB format or even "renewed" an EPUB library book that I still had loaded on my reader, so I can't say exactly what would happen under those circumstances. I would assume that two copies would be on the disk if you bought the book or borrowed it again at a later date.  What would happen if you "renewed" a library book that had not quite yet expired (if your library even allowed that) is something I wouldn't even guess about.  Of course, if you "deleted" or "returned" the book via ADE the listing on the bookshelf would disappear even though the disk copy would still be there.

What the "small problem" with my answer might be I won't guess at either.

Cliff,

OK.... gotcha'.  We're in sync now.

Agreed.  If you return and/or delete, you don't want the file any longer so the "safety" of keeping a file on disk is counter to your intentions.
