CopyDrop for Mac

CopyDrop is a Finder-based, no-frills backup utility intended to be used for user folders, media files, applications, or documents of any kind.

The concept of CopyDrop is to make it possible to use the Finder to drag and drop folders, volumes, and files in order to make "smart" copies of them, meaning that identical items already in the destination are not re-copied, saving time. There are two modes, "replace" and "merge". In "replace" mode, any items existing only in the destination will be removed such that the result will be a destination identical to the source. In "merge" mode, unique items in the destination are untouched such that the destination contains all files that were previously there (and not in the source) plus every file in the source.

CopyDrop is fully functional without registering and paying the shareware fee, but the unregistered version has a built-in 7-second delay on launch. Registration, which costs $10.00 US, will provide a code to remove this annoyance.
