Manage Folder Permissions
Folder permissions can be used to control access to files and the actions that members can take with the files.
Members with Manage permission can add or update member permissions to allow for actions such as downloading, uploading, or editing files, and publishing markups. Project administrators have Manage permissions to all folders. See Project Member Folder Permission Levels for a full list of the specific actions supported by each permission level.
Subfolders automatically inherit the permission level of the parent folder however, they can be changed later. If changed, subfolder permissions must either match, or have a greater permission level of the parent folder.
To add or update permissions for a folder:
Click Files from the left navigation to open the Files tool.
Navigate to a folder in For the Field or Project Files.
Hover your cursor over the folder and click the More menu
then Permissions settings.
Click Add.
In the Add field, enter the names, email addresses, roles, or companies which the permission levels will apply to. You can also assign the same permission level to all project members by entering Everyone in the field.
In the Permissions field, select the desired level.
Click Add.
