DuplicateFileFinder

DuplicateFileFinder application was developed to be a small tool that will allow users to quickly find duplicate files on their computer. It does this by first iterating all files in the search paths. Any files that have unique filesizes are removed right away as they could have no duplicate.
Then the partial MD5 hash is calculated for each file (a partial hash greatly speeds up the program for larger files and does not really increase the number of false matches). Then all files having the same hash are compared byte-wise to see if they are actually identical. Written in C.
Command line arguments are the paths to search, if none are given this defaults to the Documents, Pictures, Music, and Videos folders for the current user. Saves all matches into a text file and displays progress in standard output.
