Repository artifacts have multiple versions, except for jobs, job output, Interactive Reporting database connection files, shortcuts, Web Analysis artifacts and Financial Reporting artifacts.
Typical files are collections of versions, even if you have not imported multiple versions. When a file is imported, the resulting artifact is a collection containing a single version. You can later import additional versions.
Versions can be revisions of the same file or completely different files. If the file is considerably different from the original file, you should import a new file with a unique name.
Click an artifact’s name for the latest version. When you move or delete an artifact, versions are included in the operation.
Versions have their own properties that are distinct from the properties of their collection artifact.
