A few of the Display folders may need a little explanation:
The .raw folder contain all columns as dimensions – including columns that would normally be regarded as measure columns. This can be useful e.g. if you are analyzing a survey where survey participants have rated statements with a score 1 to 5. With the .raw dimension you would be able to categorize data by score value.
E.g., in this screenshot, Amount.raw has been used as a dimension together with the *.cnt measure.
The information we see here, is that the file contains in total 4,198 records, and that the Amount value of “55,2” appear in 24 of those records.
In the cnt measure folder you will find count measures for each dimension and measure, but these are by default distinct counts. Only the *.cnt will give a full count.
