  What it is
USBDLM is a Windows service that gives control over Windows' drive letter assignment for USB drives. Running as service makes it independent of the logged on user's privileges, so there is no need to give the users the privilege to change drive letters.
It automatically solves conflicts between USB drives and network or subst drives of the currently logged on user.
Furthermore you can define new default letters for USB drives and much more.
It works on Windows XP to Windows 11 and Server 2003 to 2022.

  What it is not
USBDLM isn't a wonder tool. If Windows has problems with the USB drives itself then USBDLM cannot fix it.
Here are some tips for solving problems with USB drives.

  Getting Started
When a removable drive (USB flash drive, flash card reader, portable hard drive) is attached for the first time, Windows mounts it to the first available "local" drive letter. If there is a network share on this letter, Windows XP will use it anyway for the new USB drive because since XP network shares are specific to the current user and not visible in the "System" context where the letter is assigned. The USB drive then appears to be invisible. This is fixed by XP-SP3 in most situations.
Windows can save only one letter per drive and one drive per letter. Therefore the assingments often overwrite each other, especially on low letters near the first available ones.
You can change the letter assignments in the Windows Disk Management Console with a lot of mouse clicks but you have to do it again for every new device.

USBDLM can for newly attached USB drives

  • check if the letter is used by a network share of the currently logged on user and assign the next letter that is really available
  • reserve letters, so they are not used for local drives
  • assign a letter from a list of new default letters, also dependent on many different criteria as the active user, drive type, connection (USB, FireWire), USB port, volume label, size and others
  • extract the letter from the volume label
  • assign letters for a specific USB drive by putting an INI file on the drive
  • remove the drive letters of card readers until a card is inserted
  • show a balloon tip with the assigned drive letter(s)
  • define autorun events depending on many different criteria
  • activate a basic protection against 'BadUSB' devices; USBDLM can ask on arrival of a USB keyboard or network device if it shall be activated
  • many other things, see help file, available online as HTML version too
All functions are applied to USB drives at the moment they are being attached, when the USBDLM service starts up and when a user logs on.

USBDLM runs as service under Windows XP, Vista, Windows 7/8/10/11 and all their Server Editions.


Unzip the distribution file (USBDLM.ZIP) file to "C:\Program Files" (a USBDLM folder is included).

Then execute the _edit-ini.cmd which creates or opens the configuration file, the USBDLM.INI. Make some setting now or later, e.g. by entering default drive letters for USB drives in section [DriveLetters].

Then register USBDLM as Windows service and start it by executing the


You can change the USBDLM.INI without restarting the service because it's checked for changes each time a new drive is attached.

You can deregister the USBDLM service by executing the

Both can be done without the message box by using the following USBDLM commandline parameters
USBDLM -silentregister
USBDLM -silentderegister

It returns Errorlevel 0 on success, 1 on failure.

You can stop and start the installed service by means of the _service_stop.cmd and _service_start.cmd and of course by "net stop USBDLM" / "net start USBDLM".


Running without a configuration USBDLM only prevents that a new drive gets the letter of a network share or a subst drive of the currently logged on user. It remounts then to the next letter that is really available.

USBDLM is configured thru a text file, the USBDLM.INI. The USBDLM.INI is read from the folder of the USBDLM.EXE.
If required, read at Wikipedia how INI files work.

New default letters for new USB drives (flash or harddrive)

Have a look into the help file USBDLM_ENG.CHM for more details. If you get the "cannot display the webpage" error then the help file has the NTFS file attribute "downloaded from untrusted source" and Microsoft doesn't trust its own CHM file format. To fix this, right click the USBDLM_E.CHM, select Properties and click "Unblock".
The help file is available online as HTML version too.

Card Readers

The typical 20-in-1 card reader eats one drive letter for each of its slots - if we own a card for or not. USBDLM can remove the reader's drive letters until a media is inserted.

USBDLM assigns then a drive letter as configured. If you need different drive letters for a multislot cardreader, then use the criterion "DeviceType" in a DriveLetters section (MSCR is short for MultiSlotCardReader):

Network drive letters

You can prevent Windows mounting local drives to certain letters by putting them into section NetworkLetters. This is especially useful for letters of network shares which Windows may assign to USB drives while booting. Do not configure other letters than network, subst and TrueCrypt drives here!


Balloon Tips

USBDLM can show a balloon tip with information about the drive letter(s) or mount points used for a just attached drive:


There is much more USBDLM can do, just take some time and read the help file...

V5.5.11 (30 August 2023)

  • Bugfix: V5.5.10 did not register for volume notification, so almost nothing worked
V5.5.10 (25 August 2023)
  • New: "PortableBaseLayer" system volume is ignored
  • New: UsbDriveInfo shows hidden disks
V5.5.9 (09 July 2023)
  • Bugfix: Sometimes too large icons in the balloon tips
  • Bugfix: Some graphical glitches in UsbDriveInfo on high DPI scalings
V5.5.8 (21 May 2023)
  • New: New function "uninstall a USB device" for the command interface
  • New: BalloonTips and UsbDriveInfo look better on high DPI scale
  • Bugfix: Criteria VolumeLabel did not work in [OnArrival] for manually unlocked Bitlocker volumes
V5.5.7 (22 Jan 2023)
  • Bugfix: USBDLM may crash when arrival and removal events are triggered in fast succession for the same drive
  • Bugfix: UsbDriveInfo showed a messagebox after writing a report by command-line
  • Bugfix: UsbDriveInfo showed "Error path not found" on Tools -> Compact VHD
V5.5.6 (13 November 2022)
  • Bugfix: USB High-Speed devices reporting a USB version 2.1 no more assumed being SuperSpeed capable
  • New: The MSIs creating an entry in "Programs and Features" aka "Add/Remove Programs"
V5.5.5 (04 September 2022)
  • Rollback: As before V5.4.9 USBDLM ignores the GPT attribute GPT_BASIC_DATA_ATTRIBUTE_NO_DRIVE_LETTER (Bit 63). Background: I had no idea where this attribute comes from. It turned out that this attribute is often not set intentionally, it is set by the Windows Disk Management when a drive letter is removed. This makes no difference on the computer where it is done but the drive will get no letter assigned on any other Windows computer by default too. When this behaviour was implemented 20 years ago portable drives > 2 TB (which need GPT partitioning) where probably beyond imagination...
  • New: UsbDriveInfo can edit GPT partition attributes (right-click on a volume -> Edit -> GPT Partition Attributes)
V5.5.4 (01 August July 2022)
  • Bugfix: USBDLM since V5.5.2 removed the drive letter of GPT partitions with the attribute in bit 63 set (GPT_BASIC_DATA_ATTRIBUTE_NO_DRIVE_LETTER, diskpart calls it "nodefaultdriveletter"). Now USBDLM just does not touch the drive letter of such volumes. As before you can let USBDLM ignore the attribute by IgnoreNoDefaultDriveLetterAttribute=1 in section [Settings]
V5.5.3 (25 July 2022)
  • Bugfix: USBDLM.msi V5.5.2.x failed to update any older installed version

  • Bugfix: Under Windows 8, 10 and 11 OnArrival for Bitlocker drives was executed immediately instead after unlock. Now twice, see Bitlocker.
  • Bugix: UsbDriveInfo could not swap or steal drive letters since V5.4.8 because it showed a OK only messagebox instead of Yes/No which is hard to answer with Yes.
  • New: USBDLM's balloon-tips and UsbDriveInfo look better under Windows 10 with a display scale > 100% (they are "DPI aware" and therefore no more bitmap-scaled)

For home users I suggest the ZIP file. Just unzip it to "C:\Program Files" and run the _service_register.cmd - this registers USBDLM as Windows service and starts it.
The _edit_ini.cmd opens the configuration file USBDLM.INI with admin privileges in the Windows text editor, if there is no USBDLM.INI it creates one first, containing some basic settings.
The MSI is for admins who want to deploy the software in their network. An MSI with integrated USBDLM.INI is not difficult to create, see USBDLM help under Creating an MSI. There is also some information about using the MSI for USBDLM updates.

The software is fully functional and does not expire. There is no 'full version'.
