{{Short description|Computer file system}}

A '''versioning file system''' is any computer [[file system]] which allows a [[computer file]] to exist in several versions at the same time. Thus it is a form of [[revision control]]. Most common versioning file systems keep a number of old copies of the file. Some limit the number of changes per minute or per hour to avoid storing large numbers of trivial changes. Others instead take periodic snapshots whose contents can be accessed using methods similar as those for normal file access.
