Windows 8 has the built in feature called „File History“.
It's intended use, as the name let one assume, is to store a revision history of documents. So if a mistake happens during editing files, the user can restore a previous version.

What it is not ment to be, is a backup service, which can restore the files on a new PC, e.g. in the case of a damaged or stolen PC.

This tool implements a very simple way, to restore the files from an external hard drive onto any computer running windows. Since the folder structure of the file history is the same as of the origin ¹⁾, and all the files just get a date-time-suffix in their filenames, this tool just keeps the most recent version of the files, and deletes all the older revisions.

Since File-History is not ment to be a backup, some mistakes happen, when folders/files had been moved or renamed. If this is the case for your File-History drive, then you will get duplicated folders/files, where only one of them has the most recent verion restored!

Apply the software only to a copy of your File-History-Drive! In the case of any missbehaviour of the software, important files could be permanently deleted!
