Tried it. Some of the sample corrupt docx work OK with your echo suggestion, but not the ones that usually prompt for answer about a split. Those are going into a race condition with the new echo command repeating ad infinitum:

Could not find or open
  I:/socrtwo/Documents/Word Processor/docx/repairable/Ray_of_Hope_Chri
+s_edits.dz01

Hit c      (change path to where this split file is)
    s      (skip this split)
    q      (abort archive - quit)
    e      (end this archive - no more splits)
    z      (look for .zip split - the last split)
 or ENTER  (try reading this split again):
[download]

Will try the other suggestions in a minute.
