Constant backup, causing the C disk to be full, so you want to modify the default path of the backup.
The C disk virtual machine files all cut the e-disk, open the virtual machine directly error, on-line search for a half-day did not find useful, are very troublesome input some commands, or change the registration and so on.
Next talk about my method of modifying success:
1.C User (name) there is a VirtualBox VMs folder, which is very large. Move this folder to the path you want to migrate to.
2. Modify the default virtual machine path in the global settings in the virtual machine to the path you want.

4. Open the virtual machine and you will see that there is no error.
