DriveLetterView

DriveLetterView is a lightweight and portable software application that enables users to edit drive letters and perform other useful operations, such as running a drive speed test.
Since installation is not a prerequisite, you can put the executable file anywhere on the hard disk and just click it to run.
There is also the option of saving DriveLetterView to a USB flash disk or similar storage unit, in order to run it on any PC with minimum effort and no prior installers.
An important aspect to take into account is that the Windows registry does not get updated with new entries, and no extra files are created on the disk without the user's consent.
The interface is made from a regular window and intuitive structure, where a list with all drive letters is immediately loaded at startup. Shown information includes drive type, name, description, connection status, instance ID, file system, volume name and serial number, and so on.
All you have to do to alter the drive letter is write a new one instead. Performing a speed test requires you to select the drive, write and read speed.
In addition, you can create a report with all or selected items and export it to HTM, HTML, TXT, CSV or XML format, use a search function instead of browsing through very long lists, as well as open a device's entry in the registry, to name the most notable options.
DriveLetterView runs on low CPU and RAM, so it does not hog system resources. It shows accurate drive details and successfully changes drive letters. There were no problems during our evaluation. Thanks to its intuitive layout and overall simplicity, DriveLetterView should please all user levels.
