File Types Restriction On Upload
This allows the site administrator to have control on either having only certain file types be allowed to be uploaded, or the ability to block certain file types from being uploaded.
With the Filter off all file types can be uploaded.
With Allowed File Types only files that match the extension can be uploaded.
With Blocked File Types, these file types will not be uploaded.
We also have the option to upload files including files with no extensions.
