Employing a virtual archive file (VAF) to improve access efficiency to files stored on sequential-access media. A rule is received for identifying a plurality of files existing on a sequential-access medium which are to be accessed as a single archive file.

Content metadata of the virtual archive file, which contents metadata includes identifying information for each file in the plurality of files, is dynamically generated based on the rule. In response to an instruction to perform a read-only operation on the virtual archive file, the read-only operation is performed on the plurality of files as a whole.
