If you receive the above message while trying to save your drawing, it means that you don't have enough privileges to save to the Drive/Folder where your EFD file is stored.
You can fix this in 2 ways:
- Get your IT dept. to change the privileges of the folder so you are able to move, edit and delete files (recommended).
- Save the drawing to another location where you are not restricted, such as your local hard drive.
