You should check for updates to Recuva regularly, so you have the latest version that can do the best job when it recovers your valuable files.
Note: You can only check for updates when Recuva is in Advanced mode. To switch from Wizard mode to Advanced mode, see this topic.
To check for updates, click the Check for updates... link at the lower right-hand corner of the Recuva window.
A window will appear indicating that you have the latest version, offering an update directly through the program in the paid versions of the software, or will offer to open the update download page if you're using the Free version.
