How do I delete file fragments?

[bkidwell]

I attached a file and then I deleted the reference to it in its parent text fragment. It still exists on disk.

How do I find and delete this orphaned file fragment? Is there a command to delete orphans? Do orphans get garbage collected automatically?

I am using Piggydb verseion 7.0

you should delete the file fragment, not only references to it in text fragments.
Then you go in trash and delete all fragments in it and also files on disk will be deleted.
