One can determine the filter that was used to select a file by using clearwin_info@('FILTER_ITEM_SELECTED'). The question is: Can one set the initial filter item to a value other than 1?
My question regards when the user must select two files for processing. Typically, they would select the same file extent for both files. Having the ability to set the initial file extent would be very helpful to reduce the effort of the user.
I think the variable in the MSDN structure would be nFilterIndex.
