What is a drive letter?

A drive letter usually means an alphabetic character that’s assigned to a partition on your PC. There’s only one unique drive letter for each partition, which is an alphabetical identifier to the partition itself. The drive letter varies from A to Z. However, you’re not allowed to assign the same drive letter to 2 or more different partitions. Drive letter A and B are often given to floppy disks while the hard disk partitions are assigned with drive letters from C to Z. For instance, the partition where the OS lies is often assigned with C by default while other data partitions are assigned with D, E, and F.
