You can specify any location as the user data directory. The default directory is Documents\Micro Focus\Reflection\.The directory you specify will be added as a Trusted Location.
To set the user data directory
Run the Reflection Setup program as shown in Install Reflection on a Workstation.
On the Reflection Setup program, click File Location, and then under Default user data directory, browse to the directory you want to use.
NOTE:This change only affects those features that you include in your initial installation. If you add a feature later using Programs and Features (or Add/Remove Programs), that application will use the original default directory ( Documents\Micro Focus\Reflection\), not the value you specified for Default user data directory.
