- Stop the Bandwidth Manager service
- Navigate to C:\ProgramData\SoftPerfect and move the entire Bandwidth Manager folder to where you want it to reside.
- Open a command prompt as Administrator.
- Type mklink /D "C:\ProgramData\SoftPerfect\Bandwidth Manager" "D:\NewLocation\Bandwidth Manager"
- Click the newly created link in Windows Explorer to make sure it's working and taking you to the new location.
- Start the Bandwidth Manager service.
