CloseReview for Remove Duplicates by boardtc
Rated 5 out of 5 stars
Unbelievable!!! For years, my inbox has been dragging, constantly buffering with 17+GB. Only today when using WindDirStat to see what folders were biggest I discovered duplicate mails. I started deleting by hand, but there were so many. I looked for an add-on and found this. I ran it, it crashed about 10 times but it deleted all my duplicates eventually!! The Profile size is down to 7.7GB. I'll see how the performance goes but I am very hopeful
