FreeFileSync open source development has released FreeFileSync, a synchronization utility for Windows, Linux and Mac OS X. FreeFileSync is optimized for both CPU and File I/O performance. On an older PC, the software can scan a hard drive with 200,000 files in less than three minutes. On a new PC with an SSD drive, the same scan takes about ten seconds.
FreeFileSync works with local drives, external drives, and over a network. Simply choose the two directories, compare them, select synchronization settings, and click one button. FreeFileSync has features usually only found in paid applications. FreeFileSync can copy locked files, perform binary file comparisons, and configure the handling of symbolic links. The software can handle two-way synchronization challenges such as detecting conflicts and propagating deletions.
Users can automate their synchronization tasks by running FreeFileSync as a batch job. FreeFileSync supports long file paths with more than 260 characters. For more information, or to download the software, visit http://freefilesync.sourceforge.net/
