I was using QuickCode on one machine and wanted to move my commands to another machine.
I didn't find it in documentation, but I was able to find setiings file as C:\Documents and Settings\MyUSERNAME\Application Data\QuickCode\QuickCode.xml.
I've copied the file to the different machine to the same directory and it works.
UPDATE: a new free 2008 version is available. See also my post "QuickCode.Net new TAB shortcut key"
