Configure File access rules to allow or deny access for the entire server.
Banned files are files that can't be accessed on the server.You can specify file/path mask (?, * supported) : *.jpg, c:\path\images_200?\
Using this form, you can define rules for the entire server to allow or refuse access according to file names.
If you do not specify any file/path, all users will be able to access all the files on the server. But if you set an allow list, all users will only be able to access the files in the list. If you set a deny list, all users can access all the other files except those in the deny list. The order of the rules is very important too.
For example
Allow *.rar
Can not access/store any files except *.rar.
Deny *.zip
Can access/store any files except *.zip.
Rule list
The rule list shows the current list and order of file access rules. Rules can be added and removed from the list using the Add and Delete buttons.
Also, the order of the rules can be altered using the Up and Down buttons on the right of the rule list.
Supported wildcards
To define access rules, you can use the wildcards ? and *.
Priority
The server's File Access list has priority over the domain's.
