archive (redirected from Digital archive)

(1) A file that contains one or more compressed files. Most archive formats are also capable of storing folders in order to reconstruct the file/folder relationship when decompressed. See archive formats.

(2) To compress one or more files and folders into a single file for backup or transport. Although archived files may remain on the same computer, the term implies data retention, and archived data are typically stored in a secondary location for backup and historical purposes. See archive program, archive formats, backup program, active archiving and HSM.
