Uniq Copy

UniqCopy scans a source folder to get a list of all the files and then guesses duplicated files based on file name and file size. Using this information, it copies all files to the target folder, maintaining the relative structure of the files within the target folder.

Files considered to have been duplicated in the source folder are copied only once to one of the matching locations in the target folder, and the other locations are skipped.

A summary of these "skipped duplicates" is kept in an internal JSON file format, in the target directory. The file is named file-dedupe-log.dat.
