Duplicate File Finder

[Yellows]

It compares filesizes as well to narrow it's search, instead of comparing each individual file to every other file and looping through the NTFS filesystem that way. This makes it much faster. Because if something is a different filesize, obviously there's something that deviates between the two files in terms of binary data, and therefore the MD5 is NOT going to be the same anyway.

Well, does it only compare files that are the same size or similar sizes?
If similar, you could change it to the same to make it even quicker, correct?
