' modRecyle
' This module contains code for recycling file or folders to the Recycle Bin.
' The procedure Recycle will recycle any file or folder with no restrictions. The
' procedure RecycleSafe prevents recycling files that are marked as System files
' and prevents the following folders from being Recycled:
' This File
' Any root directory
' C:\Windows\System32
' C:\Windows
' C:\Program Files
' My Documents
' Desktop
' Application.Path
' ThisWorkbook.Path
' These restriction apply only to the folders. You can still delete any individual
' folder within these protected directories.
'
' The file specification provided to either function must be a fully qualified path
' on the local machine. Partial paths and paths to remove machines are not allowed.
