At various places in the GeoQO documentation, $HOME is used. $HOME/.geoqo is the default place where all your personal configuration files, databases, scripts, etc are kept. The actual location of $HOME varies depending on the system type.
Unix (including Linux)
$HOME should be the system place for your personal files. You can use the tilda (~) as well. IE:
> cd ~/.geoqo > ls [...]
I think that $HOME is normally C: on windows. So that your geoqo directory becomes: C:\.geoqo
Mac OS X
I Don't know. Help?
What's in $HOME
The directory structure of $HOME can contain any of the following:
$HOME/ config (configuration file) scripts/ (directory of where personal scripts can be kept) mem/ (directory of "memory files") export/ (export specfic memory files) import/ dbs/ (where your geoqo database files are stored) temp/ (where temporary files are created)
