If your office computer is managed by an IT staff, odds are that your documents and files aren't located on your C: drive. Instead, "My Documents" is redirected to another location -- probably a network drive -- to improve your PC's performance and make it easier to do routine backups. If you manage your own files, you should do the same, especially if you have a small C: drive and worry that you might someday run out of room.
- Choose another location to host My Documents. Ideally, pick another physical drive on your computer, but a separate partition will do as well. Create a new folder there and name it My Documents.
- Right click on My Documents and choose Properties.
- Click Move.
- Navigate to the root of the new location you chose in Step 1 and select the empty My Documents folder you created.
- Click OK. When Windows asks if you want to move your files there, say Yes.
