The default setting of the autoloaddir property is[CORTICON_WORK_DIR]/cdd where [CORTICON_WORK_DIR] is the absolute path of the work directory, typically C:/Users/{username}/Progress/Corticon x.x

You can specify a preferred location in the brms.properties file in the form: 
com.corticon.ccserver.autoloaddir=path
where path is your absolute path delimited with forward slashes.
