Is it safe to transfer files from C drive to D drive?

When your C drive gets full, obviously, there are two possible ways to solve the issue. One is to move unallocated space to C drive to extend it, and the other is to transfer files from C drive to another drive like D, E, F, or G drive to make room for C drive. If you do have unallocated space on the hard drive, it is a good idea to try the first solution. However, given that you have redundant space on D drive, the second way perhaps is more direct and simple.

Is it OK to do this? Actually, it depends on what files you’re about to move. In general, system related files cannot be moved to another drive because they have to be stored with system programs. You are allowed to move following files:

  • Programs files like Facebook, Photoshop, Movie Maker, installed games, etc. that you downloaded from website and regarded as third-party software.

  • Personal files you created or download in “My Documents” folder, such as photos, movies, music, texts, and so on and in “Desktop” folder.

Please note that some certain programs have to be installed on the root drive of the hard drive. That is to say, they only work when installing on C drive and do not give an option to change location during installation. Please backup Program Files beforehand in case data loss caused by inappropriate operations.
