Record identifier (the word “filter”)
•
Filter type

Value specification (one or more fields, separated by commas, in the same
format as is used by the

One filter control record exists for each filter that was applied to the current

Data file
A data file contains the data for a single view recorded during a session. The
file name is dsessionid_viewnumber_viewname where:
•
sessionid is the unique identifier for the session.
•
viewnumber is a number greater than or equal to one that reflects the order
in which views were defined for the session.
•
viewname is the user-supplied name for the view, truncated if necessary to
conform to the file-naming conventions of the current platform. On the
Windows NT platform, the file name is limited to eight characters.
One record in the file exists for each unique combination of data item key field
values that occurred in each sample taken.
