Example:
StartListen("D:\", callback)
mkdir "D:\Temp" // should not trigger callback
create file: "D:\Temp\New Text Document.txt" // should callback as "D:\Temp\New Text Document.txt", but now it callback as "Temp" only
mkdir "D:\Temp\abc" // should not trigger callback
create file: "D:\Temp\abc\New Microsoft Excel Worksheet.xlsx" // should callback as "D:\Temp\abc\New Microsoft Excel Worksheet.xlsx", but now no callback triggered.
Example: StartListen("D:\", callback) mkdir "D:\Temp" // should not trigger callback create file: "D:\Temp\New Text Document.txt" // should callback as "D:\Temp\New Text Document.txt", but now it callback as "Temp" only mkdir "D:\Temp\abc" // should not trigger callback create file: "D:\Temp\abc\New Microsoft Excel Worksheet.xlsx" // should callback as "D:\Temp\abc\New Microsoft Excel Worksheet.xlsx", but now no callback triggered.
