How To use Guiffy from Linux KDE

From Linux KDE you can select two files or two folders, and then select a Guiffy "Action" added in the context menu (right click) to do a Compare.

Here's how to setup Guiffy as an "Action" in KDE's context menu:
Edit the "compare_with_Guiffy.deskop" file in your Guiffy install folder. Verify the "Exec=" path matches where you installed Guiffy. Then, copy "Compare_with_Guiffy.desktop" to your KDE configuration: "~/.kde/share/apps/konqueror/servicemenus". You may need to create this path if you haven't added other KDE Actions.

Here's how to do file or folder compares from KDE:

Click on one file/folder to select it.
Ctrl-Click on the other file/folder to select it.
Then, Right-Click on the last file/folder, in the context menu move the cursor to "Actions" and click on "Compare with Guiffy..."
