Why does System Restore delete some downloaded or saved files during a restore?
A. As System Restore monitors a core set of specified system and application file types, any downloaded or saved file which has an extension type monitored by System Restore (e.g. .exe, .dlls) and stored on a monitored drive will be lost if restoring to a point prior to the download or save. If you do not want to lose files with a monitored extension due to a restore, you should move these files to the My Documents folder or to a non-monitored partition not restored during a restore process. If you have unknowingly deleted some files due to a restore on your system, you can always recover them by undoing the restore process in question.
