[Update] Automatically and Silently Copy Files From USB Drive to Hard Disk

Thanks Biswajit Das for this method. New and easy method here -

Recently i came across a problem of usb attacks and many other incidents which made me present this article before you. I had also another wish to secretly copy the teachers usb pen drive contents so that i  can get every slide which it is very difficult to obtain.
It might be possible to accomplish this using a simple file backup program that periodically checks the USB drive for new files, and if found, copies it to a directory on your hard drive. But it’s not foolproof. Today, I discovered a better solution – using a free program called USB Spy.
USB Spy is a spying program that automatically and silently copies the content of a USB Flash drive to the hard disk when it attached to the computer. The file copying begins soon after the Flash drive is inserted. No further coaxing or button click or any user interaction is required. There is also no notification of any kind when the copying operation starts and completes. The entire thing is stealthy and very sneaky.
To make this work, you have to make sure that USB Spy is running before the thumb/pen drive is inserted, and that you have specified where you want the contents to be copied in your hard drive.
You can then hide your program which will remove the program icon from the taskbar. You can still see it running using Task Manager or any other process viewer. There is also a hotkey combination to bring up the program window but I didn’t have any luck with that one.
The contents of the USB drives are copied to the target directory and neatly organized into folders with date and size stamp. Here is the how the target directory might appear after 4 different thumb drives were connected at different times.
New Version of USB Hidden Copier has been released. Please see here for the latest features.
This software will copy all the contents of all the USB drives that have been inserted in your computer and will save it to your hard drive.
1. It is totally invisible and masked enough in order not to be detected easily.
2. It will copy only a maximum of 8GB that is enough space  and information will not fill out all hard drive space if you can not monitor it for a long time.
3. Content is saved in a folder named as the USB Drive name so you can find easily who is the owner of USB copied.
4. It starts at computer startup.
5. First copy is made 3 minutes after computer starts and then every 10 minutes the content will be overwritten, so you will have always lastet content of that USB.
6. With it’s Control Panel you can easily manage it.
7. Content copied is saved in the directory: “C:WINDOWSsysbackup”
8. The copier program is called “systemidle.exe” in order to mask it.
9. In order not to copy you own USB Drive you can create a file named “friendflag.winxp” and put it directly on your USB (this file can be also with hidden and system attributes so you will not delete it accidentally). So when the program finds this file it will not copy the drive when it is located (your USB).
