DriveLetterView enables you to view a list displaying all drive letter assignments in your system - from local drives all the way to USB drives.
DriveLetterView permits you to quickly change any USB device's drive letter. You also have the ability to delete the drive letter of any USB device that may not be currently plugged in. It will then allow you to easily export the list of all the listed drives into text/CSV/HTML/XML file.
Using DriveLetterView to change the drive letter of USB device or remote network drive is accomplished by simply selecting the drive letter and then utilizing the 'Change Drive Letter' option (F9). To remove the assigned drive letters of USB devices that you don't use anymore is equally simple. Select the desired drive letter, and then choose the 'Delete Selected Drive Letter' option.
Keep in mind; DriveLetterView doesn't allow you to change or remove a drive letter from a local hard-drive, and you are not permitted to modify an existing drive to a drive letter previously assigned to another device.
