In [[computer data storage]], '''drive letter assignment''' is the process of assigning alphabetical identifiers to [[volume (computing)|volumes]]. Unlike the concept of [[Unix filesystem|UNIX]] [[mount point]]s, where volumes are named and located arbitrarily in a single hierarchical namespace, drive letter assignment allows multiple highest-level namespaces. Drive letter assignment is thus a process of using letters to name the roots of the "forest" representing the file system; each volume holds an independent "tree" (or, for non-hierarchical file systems, an independent list of files).
