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):
Will try the other suggestions in a minute.
