Dont start upload for blocked file types
Created by: domacikolaci
Tried uploading a .exe just now and waited for upload to finish, forgetting its a blocked file type.
The service should be scanning before uploading if a file type is allowed or not before processing and uploading the file, only to at the end tell the user bad luck denied.
Seems like a waste of the users time and also a waste of bandwith/processing for the server.
