Compare 2 directory for duplicate files. (including recursive directory search) duplicate is flagged if it has the same name and is the same size only. (should probably do a proper file compare in the future - the code for this is up the top commented out, but would slow the program down to some degree)
Also contains a preview of image files.
could use a polish add some features/ add some extra smarts (eg open files externally, copy paste etc) Seems to have some issues with RAW files, (EG NEF files resizing etc - this has been somewhat corrected in that if it cant resize the file it will leave it the size it is..)
