Note that system restore files are stored with the file extension exe. Restore Points are "snapshots" of your system containing files and settings, created at regular interval. Restore points are stored in the hidden System Volume Information folder on your drive. However, these folders will be inaccessible in Explorer, even if you have configured Explorer to show hidden files.
