In the mod: files ->settings there is an allowed file types, which you can leave blank to allow all file types or you can list specifically the files you want to have uploaded. However, there should really be an EXCLUSION TYPE option.
If I dont' want to allow .exe, .bat, .rar, .zip but everything else is okay, I would convievably have to list all other file types in the world to create this type of file exclusion. Logically if you have an Only Allow option, you should also have Deny Only option. This will make administration of this module much easier.
