Istina Vista i Win7 nude tzv. Previous Versions (desni klik na fajl, pa Properties), ali ne verujem da će to u ovom slučaju da upali pošto se to uglavnom odnosi na sistemske fajlove, a ne na lične dokumente
What are previous versions?
Previous versions are either copies of files and folders created by Windows Backup or copies of files and folders that Windows automatically saves as part of a restore point. You can use previous versions to restore files and folders that you accidentally modified or deleted, or that were damaged. Depending on the type of file or folder, you can open, save to a different location, or restore a previous version.
How are previous versions created?
Previous versions are automatically saved as part of a restore point. If system protection is turned on, Windows automatically creates previous versions of files and folders that have been modified since the last restore point was made. Typically, restore points are made once a day. If your disk is partitioned or if you have more than one hard disk on your computer, you need to turn on system protection for the other partitions or disks. Previous versions are also created by Windows Backup when you back up your files.
If you modify a file several times in one day, only the version that was current when the restore point or backup was made is saved as a previous version.
