We have some engineers who have a SolidWorks license of thier own at home and would like to work with files from the vault. I understand that there is an "off-line" mode that allows users to work on checked out files in the local cache. Is there a safe way to copy or move those files to a jump drive for work on another PC?
Not sure what you mean, there should be nothing restricting you from copying the files off of the drive.
I think you should consider checking the files out before making the copy so you know that they aren't being modified while they are off-line.
