It's in your user profile...
of course in non-english versions of windows the directory names changes (unfortunately) ...
a universal approach, working on a command prompt on all localized windows versions could be:
make a commandfile: maybe called "cbhome.cmd"
=[cbhome.cmd]=
SET HOME="%HOMEDRIVE%%HOMEPATH%"
%HOMEDRIVE%
cd %HOME%
cd .CodeBlocks
=[/cbhome.cmd]=
execute your "cbhome.cmd" to change to your .CodeBlocks home-dir
