How do you previously open the *.jpg file ? Double clicking on the file ? If that was the case, then the *.jpg extension was associated to PhotoShop app. If now you can't open it that way and have to resort to opening it via PhotoShop, you may have lost the association.
To change it, WinExplorer -> Tools -> Folder Options -> File Types -> search for JPEG -> select change -> select PhotoShop.
If you're not referring to file association, then ignore what I mentioned :embrass:
