File Sync

File Sync is an easy-to-use program that enables you to seamlessly synchronize the contents of two folders. This means that any missing files from one directory will be copied to the other one, and this task is performed until both locations have the same file.
It can be used as a quick security measure to keep files up to date, especially if you want to create backups on external storage units, unplug the devices, and take them with you on your way out.

Prerequisites and interface

The entire application's packed in a single .exe file that can be saved to a custom folder on the disk or to a USB flash drive, in order to effortlessly launch it on any PC. It doesn't create other files on the disk without your permission or add new entries to the system registry. However, you must have .NET Framework installed, since it was developed with the aid of this platform.
As far as the GUI is concerned, File Sync opts for a standard .NET Framework form and doesn't put emphasis on graphical elements, preferring to focus on straightforward functions instead. All options are visible in this panel, so you don't have to depend on multiple windows and waste time looking for buttons to carry out tasks.

Sync two directories or upload to Amazon S3 Bucket

After indicating the two directories, you can start the file sync job with the click of a button. During this time, you can view log details, such as the size and full path of each processed file.
The utility comes equipped with an option for uploading folder contents to an Amazon S3 Bucket account instead of syncing the files with another directory. It can be asked to downloaded any missing files from that account too, but this is optional.

Evaluation and conclusion

Although it hasn't received updates for a long time and remained in beta development stage, we haven't experienced compatibility issues with newer Windows models in our tests. Synchronization jobs were executed fast while system resources usage remained minimal.
To conclude, File Sync may not be as attractive or feature-rich as other similar tools, but it delivers as speedy and uncomplicated solution for syncing the files of two directories, or a folder with an Amazon S3 Bucket account.
