The easiest way to manage your programs in your startup folder is to use shortcuts (icons). You can create a shortcut for any program just press right click, select new and select shortcut.
Please note, you need to create the shortcut from this folder, or you can also copy other shortcuts to this folder.
Now you need to set a location where the shortcut will point at. You can do this by pressing the ‘Browse‘ button during the Create Shortcut dialog.
At this very moment you should see the freshly created file in your (startup) folder.
Good to know, the shortcut file extension is lnk (LNK). It is used by the Microsoft operating system to point to an executable file. LNK is the short form of LINK. It’s just a direct link. The easiest way to find a shortcut is to check a mini arrow icon on the icon. Of course there is an option to hide this arrow symbol.
