I know you can select the "allowable extensions", but is there a way to just list the file types you "don't" want to allow? I only want to restrict it from uploading php and javascript files. with the "allowable extensions" I would have to think of every possible file type on earth and list them all. is there a way to just "restrict" what I want to disallow? please help.
AFAIK, there's no way to blacklist files. You can use the checkScript and onCheck settings to check the file type server side before starting the upload.
