FreeFileSync Overview
FreeFileSync is a folder comparison and synchronization utility from Zenju for Windows, macOS, and Linux. This page links to the official FreeFileSync 14.9 packages: the Windows setup executable, macOS ZIP package, and Linux x86_64 tarball published from FreeFileSync's download directory. The standalone packages are useful for backup workstations, portable admin toolkits, and offline deployment where the full installer needs to be saved before setup. FreeFileSync compares folders, previews synchronization actions, and supports common backup and mirror workflows. To install offline, download the package for the target platform, copy it to the destination computer or deployment share, and run the Windows installer or extract the macOS/Linux package locally.
