Sync Checker

Sync CheckerSync Checker is a diagnostic application which can check if two folders or disks are perfectly synchronized, i.e. if they have exactly the same contents. When creating backup copies of valuable files, or when making sure that two computers or mobile devices work on the same set of data, the status of being “in perfect sync” can be very important. In order to be safe and to prevent loss of data, you can let Sync Checker verify whether a pair of file collections are matching exactly or not.

In other situations, it might be interesting to find differences between file sets. For example, you might like to know which files have changed on your computer, comparing a Time Machine backup of last Friday with one of last Tuesday.

After performing a sync check, Sync Checker will either confirm that all files are identical, or it will present all detected mismatches. You can browse through the differing items, analyzing exactly where a mismatch occurred, and if the differences are critical or negligible. Filter tools help you to navigate through large sets of mismatching objects. You can also create a textual report of the results which can be printed or exported.

The software is distributed electronically. You can download the product and test it before you decide to purchase a license for unrestricted usage.
