For me, toggling a ~10MB file results in the estimated size jumping around by over 100GB. You can recreate this bug by just toggling the checkboxes on a few items and seeing how the estimated size jumps around. One bug that should be fixed in future versions: On the results page when you are selecting the files that you want to delete, the estimated size that will be made available isn’t accurate. But the scan seems to get all the duplicate files and will group them by folder if all the contained files are the same (which is a really nice feature). I had to leave it running overnight to get it to finish its scan. Like past reviewers have said, it tends to take a while to scan a folder.
