Tired of having to look up which drive letter Windows assigned to his multiple USB thumb drives, one author at gHacks decided to assign each drive to its own folder nested inside a “USB” folder. Not only does it add some consistency to swapped storage, it also allows for a persistent shortcut on a Windows desktop. The short how-to: Run “diskmgmt.msc” from Windows’ Run/Start Search box, right-click on your plugged-in drive and choose “Change Drive Letter and Paths.” Then:
Click on the Add button, select Mount into the following empty NTFS folder and click on browse. Now navigate to the subfolder that you want to assign the USB drive to and confirm the assignment. The USB drive will from now on be accessible from that folder as well if it is connected to the computer.
