We have 3 computers. Each using Windows 10. We have a shared network file that is located on PC 1. I use PC3 and have no trouble opening, editing or saving files from this shared location. My boss, however, can open and edit but cannot save files. It tells him he has opened a READ ONLY file. Of course I have looked at the properties of said files and it does not have the READ ONLY checked. I don't understand how I can open a file with no issues and he opens the same file and it is READ ONLY. What am I missing?
