contextmenu - Create windows right click context menu for SPECIFIC folders

Question

How can I create a context menu that appears for files/folders inside a particular folder.
Say there is a directory "D:RandomCodes"
How do I create a custom context menu item "Open in MyApp" for any file/folder inside this? This menu item should not appear for any other directory. I know if I add the entry in HKCR/Directory/Shell, it'll work, but then it'll appear for all files and folders everywhere. Please guide me through this.

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOTFoldershellNetBeans]
"AppliesTo"="System.ItemPathDisplay:"NetBeansProjects""
@="Open with NetBeans"

[HKEY_CLASSES_ROOTFoldershellNetBeanscommand]
@=""C:\Program Files\NetBeans 7.2.1\bin\netbeans64.exe" --open "%1""
