Thank you for your answer!
I guess I will install SVN and test it out. My main concern was if it is still in development.
I just installed Perforce to test it out, but can’t wrap my brain around where it stores files.
I need to set it up to use our server (network drives), where our projects are located, but it saves a copy (or archive) of the project locally on the server(different from the NAS), that has small disk space.
I might be completely wrong about things, but that is how I understand them.
