Is there a way to open all subfolders within 2nd level of a root folder?

[Diana (Cda)]

Often enough I have a series of nested folders for applications that it would be nice not to have to manually open, which is what I've done for years (decades ...? / yes, I have a ton of Windows app ...)

Example of scenario, I'm going to try out some apps to see which might do a new, important task.  The root folder I'd input is, where the OK_click would have the syntax to open all those sub-subfolders, if I can call them that:

Root folder:  D:\BIRTHDAY\
Level 1 type of subfolder:  D:\BIRTHDAY\CDAY Calendar Almanac v0.5.1\
2nd level of actual folders I need to open:  D:\BIRTHDAY\CDAY Calendar Almanac v0.5.1\APP- CDAY Calendar Almanac v0.5.1\

So I'd input the root folder, and hopefully the script will open all subfolders beginning with "APP- ", as in the example above.

How would one do that, please?

I do have the script started here that prompts for the root folder (i.e., the "BIRTHDAY" one above):

$Label1 = GUICtrlCreateLabel("Root folder:", 16, 8, 84, 22)
GUISetIcon($IconsMine, 2)     ; this changes the GUI icon in upper left-hand corner + GUI taskbar icon to your chosen one)

GUICtrlSetImage(-1, "C:\Documents and Settings\Administrator\Desktop\Script\Clear.ico", 0)
GUICtrlSetOnEvent(-1, "ClearClick")
GUICtrlSetTip(-1, "Clear the contents of the two input boxes ...")

Thank you!
