B4J Question What Command To Use On Windows To Open A New Window Showing Directory

[B4XDev]

I've searched the forum but couldn't find how to open a new OS window to a directory. Here's what I've tried:

Private Sub btn_OpenFolder_Click
    'open the project folder
    Log("Opening the project folder: " & current_project_folder)
    shell.Initialize("shell","Open",Array(current_project_folder))
    shell.WorkingDirectory = current_project_folder
    shell.Run(-1)
End Sub

I've also tried "Start" as the Executable string in shell.Initialize.

Sub Button1_Click
    Private fx as JFX ' if not already exists in the form...
    fx.ShowExternalDocument("C:\")
    fx.ShowExternalDocument("E:\B4J")
    fx.ShowExternalDocument("E:\ORC\ORC.Delphi\ORCStreamHelper\LSE3Teams")
End Sub

@DonManfred Thank you!

Just for completeness sake, you might want to add

Private fx as JFX

somewhere to your answer just in case for new users.

As you only can use this in a UI app a JFX Object is probably already there.

I was wondering if fx was usually global or not. Oh! Just found it in Main (in a B4XPages app).

It wasn't in the class module where I put the code, so I added it to the local Sub. Should I instead make a reference to the fx in Main? What's best practice?

even in a non b4xpages - UI App - it is in the globals already.
For JFX a global Reference should be ok and standard i guess.
