FtCG includes several features:
You can download the latest version of FtCG at http://atlight.github.io. The most recent version is listed on that site. (You can check the version of your copy by clicking the "Settings..." button.)
A note on operating system compatibility: FtCG works on Windows and Linux, and most likely on Mac OS too.
For those who are interested, source code (in C#) is available on GitHub.
I would appreciate any , especially regarding the deletion of files after transfer (not being an admin, I can't really test this feature).
