Hi Henrik

With the current publicly available V0.2.3 build, not automatically, but you can either manually or by script clear the client/server folders in your cr folder (which is in your user directory). The cr\client server and logging paths are considered 'temp' locations, you can delete them.

We recently released V0.2.7 (just haven't updated the community yet) which now stores all these files in a temporary directory which is cleaned up when blender exits.

Hope this helps?

James
