Jack,
Thank you for your interest in HealthFrame.
HealthFrame does not use a single file to store the personal health record information; instead it uses a database which is stored in the standard application data for all users. In Windows XP, you'll find your database files in the c:\Documents and Settings\All Users\Application Data\Records For Living, Inc folder.
In Vista, the location starts with c:\Users instead.
Please let us know if we can be of further assistance,
Support Team
