I have a use case where the creator of an ISO file needs to make a few small changes to an 8GB ISO file comprised of many thousands of files. It would be SO nice to be able to edit the ISO collection itself, rather than recreate the ISO from scratch.
Likewise, I have a similar use case (less important) where users of the ISO need to adjust a few scripts in the ISO file – otherwise they need to extract it to HD and consume 8GB more disk space for their modified working copy. Again in this case, the ISO should be edited and re-saved for this one-time customization per user.
As the subject line says, these use cases are probably what the creator of the Macintosh DMG format had in mind – it has a mode where a DMG can be Read/Write. If this request can’t be honored using ISO format, and the DMG format is open, I’d like WinCDEmu to handle mounting and authoring DMG files, with the R/W option.
Final note: the image mounting as R/W needs to be command-line enabled too. Once the ISO/DMG is mounted, my use case needs batch scripts to be able to modify the files.
Thanks!
