Select the Permissions tab, then click the Content Access tab if it’s not already displayed. Then choose the roles you'd like to work with from the roles list panel. In the far-left column are the contents of your fileroom (click the arrows to expand the folders). The central columns display the settings for each role’s content permissions.

To change anything here, click a segmented bar and click Edit Permissions. 

Filter for specific items under the Status or File Type column, and select Permissions in the top menu. Select the check box next to the documents you wish to bulk add permissions for.

You can select up to 25 documents at one time. To select more, click the right arrow in the bottom-right of the page.

Once you’re done, click Save.
