Hi, I am having an issue where i need to copy a very large workspace to another computer (check out process takes far too long due to network restrictions). I can copy the files ok, and the plastic.selector file seems to suggest that the workspace is associated with a particular branch, but the plastic SCM gui is reading all the items as added rather than pre-existing. The gui is also not showing the 'house' symbol on the changeset, so i suspect i need to change another value in a file somewhere (ive checked all those i could find in the client folders) Does anyone know a way i can trick my GUI on the new PC to see the files copied in as actually being checked out?
