OffsiteSync for Windows

OffsiteSync is a simple application that synchronizes files and folders in two locations. The locations can be on the same machine, a network, or a remote FTP server. It uses a unique single-tree merged view to make finding differences easy. Almost every item in the interface has a right-click menu so finding the command you want is easy. OffsiteSync is a robust, easy-to-use and feature-rich data synchronization and backup utility.

Version 3.4 reduced price and added more options for "skipping" files that include wildcards and types.
