Bob, Try opening Windows NT Explorer, click on View/Options/File Types. This should get you to a screen that allows you to Edit, Remove or add a New Type.

I have accidently set up an association for files with the .hgl extension for a program AutoView. If I go to My Computer/View/Options/File Types you can supposedly change this. However once there, there is no listing for the .hgl If you delete or Edit any of the Autoview info you end up having to reinstall Autoview. If you try and make a new association with .hgl it tells you already in use as hgl_auto_file yet that is not listed in the files types either to be able to edit. Our MIS group had no answers either. All I want is to be able to undo the association of only the .hgl file type with any program and can' t seem to get there form here. TIA Bob Executone Inter-Tel Business Information Systems, Inc.
