I'm trying to open Windows Explorer using Google Apps Script.
I'm not looking for a specific folder or anything, just to open.
I run my Google Sheet in full screen mode and don't have the Windows toolbar along the bottom of the screen. Rather than F11 out each time to see the Windows toolbar to open Windows Explorer, a script would be super efficient.
I've searched and searched, and can't find any previous examples to even start the project. This leads me to believe that it is not possible.
You are looking in the wrong place. Google Apps Script server-side and client-side code cannot access the user's device. Look for Microsoft Windows settings / commands to show the Windows taskbar (toolbar) in full screen mode. If you have problems finding this command, consider asking a question about it at https://superuser.com.
Another option is looking for a utility to create your Windows keyboard shortcuts. If you have a problem finding this utility, consider asking for recommendations at https://softwarerecs.stackexchange.com
