Synology - delete or decrease file versions to free up disk space

Question

Synology CloudStation file versioning uses a lot of space so how can I free up some space? How can I see how much space file versioning used?

Answer 1

As an updated answer, now CloudStation is "Drive Admin Console". I am posting this answer just as an update and to also include some screenshots to assist anyone.

To see how much your versioning database takes up:

2. Go to Overview

   space file versioning takes.

To disable versioning or reduce the number of versions Drive keeps

1. Open Drive Admin Console
2. Go to Team Folder
3. Select your Shared folder, in this case My Drive
4. Click on Versioning
5. If you want to keep versioning, but with less versions, specify your desired Maximum Versions (2 would be enough for most cases, I think).
6. If you want to disable file versioning, un-check Enable version control

To delete your current File Versioning database:

1. Open Drive Admin Console
2. Go to Overview

8. Specify your file extensions *.extension1, *.extension2, *.etc (example *.java), separated by commas
9. Click Add
10. Go to Applied User
11. Check all users, or the ones you want to not version files
12. Click Apply
