# Upgrading RoboDemo and Captivate projects

When opening a Captivate project created with RoboDemo, it is important to note the file extension. Projects created with RoboDemo versions prior to version 4 use a .ncp file extension. RoboDemo 4 and 5 projects use the .rd file extension. Captivate upgrades older projects (those using either .ncp or .rd) as they are opened in Captivate and gives them the new Captivate file extension of .cp.

Captivate also saves backup files of the older projects in the Backups folder (located, by default, in the following folder: My Documents\My Captivate Projects\Backup). These backup files are saved before the conversion occurs, and you can open the files in RoboDemo.
