A RUPAF file is a data file used by Revo Uninstaller Pro, a program used to uninstall programs, Windows apps, and plug-ins. It contains subscription registration information, which includes the name of the user and serial number. RUPAF files are used to activate or update a subscription of Revo Uninstaller Pro if the user does not have an Internet connection.

To create a RUPAF file, click the menu button and choose "Registration" or "Update Subscription." Then, fill in the name of the user and the serial number. After completing both fields, click "Save File," name the file, and choose the location. After saving the RUPAF file, email the file to Revo Uninstaller and they will send you the "Unlock Key," which you can enter in the registration form to activate the software.
