Guiffy Diff/Merge Tool

Razor comes with an OEM license that gives the user permission to run Guiffy within the Razor Versions tool. You must first install the Guiffy tool on your system. You can download the Guiffy tool from the web site. Please note that Guiffy will only work in a 64bit environment.

If you prefer, you may purchase a separate license which allows you to run Guiffy outside of Razor.

Guiffy is not bundled with the RazorPC package. You must download and install it for each system that wants to use it. You can download the Guiffy tool from the web site. Please note that Guiffy will only work in a 64bit environment.

The Guiffy tool is not bundled with Razor on non-Windows platforms. This product and the appropriate Java runtime engine (JRE) needs to be installed by the user. The product installer and the Java runtime engine may be downloaded from

The Guiffy product can be installed in the $RAZOR_HOME directory of the Razor product under the Guiffy sub-directory. You must create the Guiffy sub-directory before installation. Also the JRE used by Guiffy, is installed under the Guiffy installation directory so that it doesn't conflict with an existing JRE installation. The environment variable GUIFFY_HOME must point to the Guiffy directory and be defined by the user prior to using the product. You can add the environment variable to the two rz_prep files. (i.e. RAZOR_GUIFFY=$RAZOR_HOME/Guiffy)
