I am using STMCubeIDE. I have tried to move the workspace to a different (physical, not network) drive, but STMCubeIDE apparently cannot handle that. It reports "Unable to access" type problems. Any thoughts?,

OK. I have discovered the answer now. The procedure is:

1. Close and delete the project from Cube (presumably without deleting the content).
2. Switch the Repository in Cube [File | Switch] (includes possibly creating a new one).
3. Cube will close and reopen.
4. Open the project(s).

After this it is all good.
