so first things first...
1. SharePoint files are accessed as a URL... http://sharepointsite/site/subsite/doclib/subfolder/file.txt... your mapped drive has a completely different format... Z:\subfolder\file.txt.... and your BROWSER has no knowledge whatsoever if the two are related
or not... so clicking a file in SharePoint will never tell a program to "link up" with your network drive.
2. files accessed directly from SharePoint (using the URL format) attempt to do so using "WebDAV"... Windows has included a WebDAV client for the last several versions... if it is working correctly, you should have no problem clicking a file in
SharePoint, opening it in ANY program (notepad, as an example, since it's effectively 20 years old and completely clueless of 'SharePoint')... but the program relies on that WebDAV component being available and functioning correctly... this is usually where
the problem lies... usually it's a matter of making sure that authentication works.
