This visualizer displays captured data from the developer's point of view: it presents the table consisting of the recorded IRPs. Each row represents one IRP and each column represents one single part of IRP.
Please, have a look at the sample table view:

Columns definitions are:
Index (#): The column contains the index of the request. The index increases in ascending order.
Time: The column contains timestamp of the request. Timestamp format can be accustomed in File ->Preferences.
Function: The column contains the name of the request. Usually it is one of standard IRP major function names.
Direction: The column contains either UP or DOWN string, that stand for the direction of the request. If DOWN is displayed, the request was initiated by the application, otherwise by the device driver.
Status: The column stores the request status.
Data: If the request has data in its body, it is displayed in this column in hexadecimal format. Number of displayed symbols is limited to 260.
Data (Chars): The same as previous column, but displays data as characters.
Note, that entries highlighting colors can be customized via
Preferences dialog.
