If you have a complex folder structure and want to duplicate it to some other location then you can use a free tool for that purpose which is very simple to use.
The tool is called Mirror and it is a freeware backup tool that duplicates a folder structure to a new location. The tool is free to use and require no installation. The tool is portable and can be used in the pen drive as well.
Mirror has three options which can be used to enhance performance:
• Synchronize Target: Items not found in the source folder will be deleted in the target folder.
• Minimize On Use: Causes the window to be minimized to the taskbar while processing.
• Auto Exit: Causes Mirror to exit after processing.
