    The title says “… and Combine Zip File” but there are no commands to combine files which have been split.
    The extract commands just extract the content from a single part of the zip-split, but not from the entire set of split archive files.

    1. Hello D H,

      In command, you need to mention only first part. As far as all the parts are in the same folder, 7-zip will extract everything.
