Thank both of you! For GecT I change the maya file to the .ma file and I just installed a Notepad text editor from internet But I am not familiar with text editor I still kind of try to figure out how to see the bad info by using text editor For stwert Yeah it is possible. Would problem of ram caused by window7 32bit? “maya application file has stopped working” is as far as error message I saw so far I still try to find the way to acquire the message by opening up the file as u mention. Thank all
