Add directory to Path environment variable

[easy-going-dependabl]

I am aware of this.

Button to add dir to %PATH% variable?

Is it possible to create a button which adds the directory actually displayed in the Lister to the PATH environment variable? (The addition would be only temporary until Windows closes). This would be very handy.

I would like to suggest a useful right-click menu option for a directory--Add to user path and add to system PATH.

You can do it using the setx command that's built into Windows:

In Opus, you should be able add something to the right-click menu for folders to run that fairly easily, via Settings > File Types.
