USB Drive Letter Manager screenshotUSB Drive Letter Manager (USBDLM) is a lightweight software written to be used under Windows OS that will give you total control over the system's drive letter assignment for USB drives. The application will run as a system service, being independent of the logged on user's privileges. Thanks to this feature, you will be able to easily change drive letters without having administrative privileges.

USB Drive Letter Manager will automatically solve conflicts that may occur between USB drives and SUBST or network drives of the current user. In addition, the program also lets you assign new default letters for your USB drives.

You should know that this application is not a troubleshooting application. If your operating system has an issue with the USB drives itself, then USB Drive Letter Manager won't be able to solve it.


  • Helps you solve conflicts between USB and Network drives.
  • Does not require any user privileges.


  • You have to edit the .ini file to configure the program.
  • Any time you edit the .ini file you have to manually restart the service for changes to take effect.
