DriveLetterView is a simple utility that allows you to view the list of all drive letter assignments in your system, including local drives, remote network drives, CD/DVD drives, and USB drives - even if they are not currently plugged.
It also allows you to easily change a drive letter of USB devices and remote network shares, as
well as to delete a drive letter of USB device that is not plugged.
You can also use DriveLetterView to export the list of all drives into text/csv/html/xml file.
- This utility works on every version of Windows, starting from Windows 2000 and up to Windows 10.
Both 32-bit and x64 systems are supported.
- In order to change/remove drive letters on Windows 7/2008/Vista, you have to right-click on

you won't be able to change/remove a drive letter.

DriveLetterView doesn't require any installation process or additional dll files.
In order to start using it, simply run the executable file - DriveLetterView.exe
After you run DriveLetterView, the list of all assigned drive letters is displayed on the main window of DriveLetterView.
If you want to change the drive letter of USB device or remote network drive, simply select the desired drive letter and
use the 'Change Drive Letter' option (F9).
If you want to remove assigned drive letters of USB devices that you don't use anymore, you can select the
desired drive letter, and choose the 'Delete Selected Drive Letter' option.
Be aware that DriveLetterView doesn't allow to change or remove a drive letter of a local hard-drive.
Also, you cannot change existing drive to a drive letter that is already assigned to another device.
If you change a drive letter of USB flash drive that is not currently plugged, this flash drive will
get the drive letter that you choose on the next time that you plug it.

This command-line option can be used with other save options for sorting by the desired column.
If you don't specify this option, the list is sorted according to the last sort that you made from the user interface.
The <column> parameter can specify the column index (0 for the first column, 1 for the second column, and so on) or
the name of the column, like "Drive Type" and "Drive Letter".
You can specify the '~' prefix character (e.g: "~Drive Name") if you want to sort in descending order.
You can put multiple /sort in the command-line if you want to sort by multiple columns.
DriveLetterView.exe /shtml "f:\temp\drives.html" /sort 2 /sort ~1
DriveLetterView.exe /shtml "f:\temp\drives.html" /sort "Drive Type" /sort "Drive Letter"
When you specify this command-line option, the list will be saved without any sorting.
