If they are cancelled they are deleted. The reason they are deleted is because they are known to contain virus/dangerous imbeded files within.

OK, that's misleading.

While it is true that downloads cancelled by Limewire may be dangerous (you have been warned) it is my personal experience that they are more frequently cancelled for less egregious issues (e.g. file extension not matching content--read this entire thread for details).

There are two ways that I have used to recover a file deleted because Limewire mis-identified it as "dangerous."

Warning: If you use either of these two methods you need to virus check the file. You are recovering a file the LW deleted because LW thought it was dangerous and it may be dangerous.

1. Undelete the file. You may have to undelete the temporary file. I've had challenges with this method since LW 5.1.3. For some reason the method LW is using to delete the file isn't leaving anything for undelete apps to pick up.

2. Stop the DL at 99% and attempt to use the temporary file.

Neither is a good solution but can be work-able.

If you do not have an undelete app then Google for one. There are numerous options and some are free (you may want to try method 2, first).

The only good option at this point is to switch to a gnutella client that won't delete your files. After all, this is a gnutella client not a virus checker. I haven't given up on LW, yet, but have been using it less because of this specific issue.

Good luck!

Correction: LW version 5.1.3 is where I first noticed the problem with LW incorrectly identifying files as dangerous. It was shortly after that when I noticed method 1 not working (sorry, I don't remember which version).
