DirSync Pro was an open-source file synchronization and backup utility for Windows, Linux and macOS.

DirSync Pro detected any kind of changes to any file/directory in the source (e.g. file/directory modification, move, deletion, renaming) and could synchronize the destination accordingly.

DirSync Pro offers these options to solve the mono-directional synchronization conflicts: DirSync Pro lets the user configure unlimited number of filters to include or exclude files and directories.

Linux.com rated the utility positively, saying that "it makes defining a bidirectional sync as simple as picking two directories".

[7] Likewise, freshmeat calls it a "powerful, easy-to-configure tool to synchronize the contents of one directory with another".
