PathSync an interactive directory synchronizer for Windows
Pathsync is a portable professional folder synchronization
utility for ad-hoc use, ideal for use on your USB stick. The utility is able to
analyze two directories, compare them to the very details, and show the user a
list of found differences.
The user can select what actions should occur (which
files to overwrite, which to delete, which to ignore), and allow PathSync to
synchronize.
PathSync provides nifty statistics during the
synchronization, so that the user is never wondering how much time is left,
etc.
PathSync is GPL free software, each download package
includes the source.
