You have the option to delete a single selected 2D measurement of the current event directory. 

First start the 2D Explorer from the WinARace main window with the shortcut key <ALT + E> or press the button <Change Event>.

Afterwards select all 2D measurements you want to delete (at the middle list view (panel).

After the measurement selection press the shortcut keys <ALT+ D> or click at the corresponding toolbar button (see figure above).

As next step you have the option (if you select "MES" directories) to select the kind of measurement deleting. This option lets you choose if you want to delete the complete measurement or only the directory called Download inside the *.MES directory. The Datalogger will be stored his data in this Download directory before he decompress and divide it into "*.MES" directories.

The default setting is to delete the complete measurement. Confirm the deleting process with <OK> or press <Cancel> if you want to cancel the operation and close the deleting window.
