dup-remover

First of all, I absolutely love the very simple GUI of this app, it was a good job and uncluttered, very straightforward. I also like how fast it loads my files and how fast it operates. When I ran dupremover.exe, it did a generally great job. I am running Windows 10 Professional 64bit Edition. Only one exception: for Remove Lines, it behaved slightly unexpectedly in one case, where you have 3 periods (like an ellipsis) on a line somewhere in the file. It moves the "3 periods" line to a different line at a different location in the file, so it ends up out of order. I am giving 4 stars because I love this app and hope to see the developer do more work on it to fix that one problem, and that would make it a 5 star app. I will try to return to check for updates. Hope this helps others to know what to expect in the meantime. Great job to the developer!
