This page lets you choose the appropriate folders for the program files and data files.
By default, Setup suggests a location for the WorkgroupMail program files and data files. This defaults to c:\program files\workgroupmail and c:\program files\workgroupmail\data, respectively. You may change either location by pressing the appropriate Browse... button and selecting a folder. Sometimes it is preferable to locate the data files in a completely different folder area from the program files for backup purposes.
Either accept the default folder locations or enter your preferred locations and press Next.
