About asset versions
Rather than replace an existing asset, you can add a new version of the asset. Note the following.
You can download, preview, or delete older versions of an asset in the Version History section.
If you delete the current version of an asset, the previous version becomes the current version.
The current version of an asset displays when users navigate the library and try to attach assets.
You cannot delete an asset version if it is the only version of the asset.
