Comment 1 for bug 1198761

The design in that screenshot is confusing, so I'd need a little help designing a replacement.

Does "Purge after" "30 days" apply to both "Automatically Empty Trash" and "Automatically Purge Temporary Files", or does it apply just to the latter that uses the word "purge"?

If it applies to both, does "Purge After" mean "Delete files older than", or does it mean "Delete all files every"?

And if it applies just to the latter, when is the trash automatically emptied?
