The Sync program must compare the source with the target and viceversa. Newer and modified files in the source are to be copied from target. Deleted files in the source are to be deleted in the target. Newer and modified files in the target are to be copied into the source. Deleted files in the target are to be deleted in the source. But all modifications are to be viewed first into a listview with a symbol (green left/right, red left/right, delete left/right, equal both page). Methode to run: copy left; copy right; purge left; purge right (only modified files, only newer files, only deleted files). Integrated exclusion file list.
Complete and fully-functional working program(s) in executable form as well as complete source code of all work done.
