SwiftCompare

SwiftCompare is a good option if you're looking for a program to compare and internally synchronize files, folders, and documents.

Basically, SwiftCompare compares two elements on your hard drive. As mentioned above, these can be files, folders, or entire sub-folder structures; whatever you choose. SwiftCompare compares the content of each one, displaying them in the dual-window interface, helping you easily locate the differences.

Every time you compare two folders or files, SwiftCompare gives you a summary of its analysis, informing you of the main differences it finds. Afterwards, you can decide if you want to synchronize the content of both elements, and how you want to do it.

All in all, SwiftCompare is a quality program that's easy to use. If you're looking to synchronize the content of two folders on a regular basis, SwiftCompare lets you do it in a short amount of time and without lots of complications.
