The file is not being skipped.
This constant exists because the UnzipPreprocessingFile or ZipPreprocessingFile events can indicate that a file is excluded or not, and when they indicate that a file is excluded (i.e.: the bExcluded parameter is True) the xReason parameter contains the xsrIncluded constant (0) – the file is not excluded, and therefore not skipped. It's a filler constant.
