I'm running Windows 7 Ultimate and my system drive (C) is a relatively small SSD. I'm looking for ways to free disk space - I have plenty of room in my other hard drive, D. Of course, since it's the system drive, most files on C are system / application files that I can't just move to D as I would regular data I have come across quite a few articles that suggest the following approach for moving folder C:\X to D:\X : 1. robocopy C:\X D:\X /E /COPYALL /XJ /MOVE 2. mklink /J C:\X D:\X I've seen such advice regarding hefty folders such as "C:\Windows\Installer","C:\Users" and even "C:\Program Files" Would there be any risk involved in such a process (assuming no user error) ? Most reports appear to be successful. If so, are any system folders less prone for trouble than others (specifically those mentioned above) ? Thanks in advance!

Bump !

Hi, Regarding system folder, generally, they can work fine. But sometimes, unexpected error could occur, such as when you are using Windows update or System Restore.

Hi yosi142, Usually, it’s recommended to not mess with system folders, which include the Windows, Program Files and Users folder.
