Is it possible to change the location of FKeySMTP directory or move it to another disk?
This directory is not movable. We must have it because of the Windows Vista and it's Virtualization scheme. That's the only way we could find to easily communicate between multiple processes using files. You can move your queue directory away from it to save the space. In the C:\FKeySMTP\Common.rep change the option IncomingQueueRoot and specify any path you need.
