Downloads Manager Access Control is one of many great features available in the pro+ edition of the CM Downloads Manager. It allows you to group users and assign access permission to download and upload files based on the group settings.
Altogether, the Downloads manager access control settings make it 10 times easier to prevent spam and malware.
The user groups definition settings are accessed using the group management interface in the plugin dashboard. This is where administrators can create multiple groups of users while defining the membership of each group from the list of users from the existing WP users table.
Once these user groups are defined, administrators can then set the permissions for each of these groups, deciding which group of individuals can add upload their own files for download and also which groups can view existing downloads.
Administrators can also grant users the option to define which groups are allowed to access the files they upload.
