I've found this link to use Document Types in the info.plist
How do I get my app to show up in the "Open In..." popover list in the iPad?
but what if I want to add any kind of file to the Document types, shoud I add "jpg,png,pdf,mov,xml,php,doc,ppt....." to the info.plist.
Is there a easy way to make myapp open any kind of file in another app?
