SABnzbd Forums

I am running on a Mac Book Pro. When files are ready to start extraction, if there is a Disc is full, sabnzbd pauses, and fails with a message, as it should. But once you free up disc space and hit the retry button, it duplicates the files that are extracted. I'll see files that are named some_file.txt and some_file (1).txt. My guess is that the files from the first extraction attempt are not deleted before trying to re-extract the second time.

They're not deleted.
Normally the new files would land in a new folder, unless you using a single folder.
There's a work-around: set Config->Special->overwrite_files on.

As you can guess, there are potential side-effects.
