Volume Shadow Copy - Old wine in a new bottle :)

Microsoft is providing the undelete system feature in Windows Vista too.. The technology, which is automatically switched on in Vista, is called 'volume shadow copy' and Vista users will see it appear under the 'previous versions' banner.

It maintains backups of older versions of files when you edit and save a new version, similar to .bak files. This feature is very helpful to retrive the files, in the case of accidental deletions.

This feature can easily be disabled via the system protection tab within the system properties control panel.
