It's based on WinSCP FAR plugin.
Yes, it is sort of based... But, unlike WinSCPFar, it does NOT work correctly. We have migrated to NetBox some time ago and since then we are encountering all sorts of issues... And the author does not seem to be bothered by any feedback :-(
At present, we are seriously considering downgrading the Far version for all our users (almost 40) who work at home to be compatible with the last WinSCPFar plugin again...
Please, do not abandon us ;-)
