Sharing is set to Read & Change for the domain user in question. I have a problem when I try to run an image file by entering its UNC path to Run dialog, or doubleclicking the UNC link in Outlook or running C# Process.Start("\\czek000lbsv015\CHO\20171010153330_1BB5442.jpg") . \\czek000lbsv015\CHO\20171010153330_1BB5442.jpg it shows Windows photo viewer can't open this picture because either the picture is deleted, or it's in a location But the file in a subfolder opens well when executed: \\czek000lbsv015\CHO\THUMB\20171010153330_1BB5442.jpg When I click on either of the files in Explorer then both open well, I can browse the folder etc. What is wrong, how to fix it? I need to open the file from a C# program. ...
