MDC to output filename from within zip file archive

[roughana]

Refer to ftp.apple.asimov.net/images/gs/sound/midi/midi1.zip It contains one file: Bach Art of Fugue.2mg Running through MDC produces the following (partially redacted at '...'):

MDC for Windows v3.0.0 (DiskImg library v5.0.1) Copyright (C) 2014 by faddenSoft, LLC. All rights reserved. MDC is part of CiderPress, available from http://www.a2ciderpress.com/. Linked against NufxLib v3.1.0 and zlib v1.2.8 ... File: midi1.zip Disk: ProDOS /BACH1 (800KB) Name Type Auxtyp Modified Format Length

ABOUTBACHFUG TXT $0000 11-Jan-94 21:37 ProDOS 1458 ...

Notice that the filename of the image within the zipfile is not output by MDC. I'd like to see that filename (Bach Art of Fugue.2mg) as it could provide useful context to the contents.

Is this as simple as adding the following? (warning, I am not proficient at cpp and know enough to be dangerous) https://github.com/fadden/ciderpress/blob/master/mdc/Main.cpp#L905 fprintf("Sub-volume name: ", subVolName, "\n");

.zip and .gz are considered "outer wrappers", which CiderPress does its best to conceal the existence of internally. It looks like the filename is held in the fStoredFileName field, but that's private, and not used for anything outside of the OuterWrapper code (it's retained so that, if you update the disk image, we have the name on hand when updating the Zip archive).

Sub-volumes are things like ProDOS volumes inside an image of a hard drive with multiple partitions, or DOS Master volumes on an 800K floppy (e.g. this).

It would be possible to expose it, but the change is not a one-liner in MDC.

This will not be addressed in CiderPress. But I think this does the trick:
