As an administrator, you can define which fields should be mandatory when uploading files.
- Hold the mouse cursor over your name in the top right corner of the screen to show the meny, then click "Configuration"

- Click on "Custom Fields"

- Here you can choose which fields should be mandatory when uploading files.

- If you scroll down, you will find a section called "Category". Here you can choose which category trees will be mandatory to fill out when uploading files.

- After you have made your changes and saved them, you must log out and back in to admin to see that the fields have become mandatory. Mandatory fields will have a star next to their names.
