You can retrieve any historical version of a connected file by downloading it.
File versions that were archived or auto submit versions that automatically collapse can also be accessed, contact your Customer Success Manager for more information.
Start by opening the file's version history (click here for more info), hover over the version you would like to access. Click on the 3 dots menu and select Download.
The version will be downloaded to your local machine (usually the downloads folder, according to the machine's settings). It will NOT replace the latest version of the file.
