Automatic deletion of file versions
Google Drive on the web keeps the latest and previous versions of a file. Keep in mind that you may need to purchase additional storage since these versions take up storage space in Google Drive on the web. However, you can change this setting so that it automatically deletes previous versions when they're older than 30 days or when there are more than 100 previous versions of the same file.
How to enable automatic deletion of file versions
- Select a file in Google Drive on the web.
- Expand the More dropdown menu and select "Manage revisions."
- Uncheck the box in the "Do not auto delete" column next to revisions you want automatically deleted.
