On the toolbar, you can add a custom button to run a script.

Two questions:
1. what language do I use for the script? I have tried several commands, but none seem to work
2. I just want to make a simple custom button that links to a specific directory on the hard drive. Any ideas how to do this?

1. XYplorer's scripting language
2. or, if this is really just a .lnk file:

but none seem to work

And which commands exactly did you use?
