File Revisions and Version Control
The OSF has built-in version control. When you add a new version of a file with the same name to your OSF project, the OSF automatically updates the file and maintains a record of all previous versions stored on OSF Storage.
The OSF also provides access to previous versions of files stored on third-party storage providers. Some storage providers limit the number of previous versions saved; check with your storage provider to understand their policies and practices related to versioning.
