Q: How to open a PPC in any system?

If you are needing to open the file in a PPC G4 or other old G3/G4/G5 non-intel Mac

then the application of the era was likely Roxio Toast (perhaps version 10.0.2?) for

use in PowerPC hardware run under OS X 10.5.8 Leopard or OS X 10.4.11 Tiger.

A light history of that product series can be found here; not so much.

There may have been a combination of other applications that could take a whack at it;

but now there's a greater divide between what was, and what's now available. Plus

changes in Roxio. ~ I had composed a better reply than this, but the Site chose to not

automatically save it; then I could not re-post it either -- so that content with links is lost.

This happens in ASC discussions, especially when attempting to post links elsewhere.

You may be able to get the ISO file and make use of that, perhaps even in Disk Utility, as

that used to offer a tool to burn content to disc media. See results of first google search

Doubt if an extractor utility such as Pacifist (charlessoft) can do that; it works with system

archives and applications installers that are orphaned or broken. The other utilities to for

use with video when created by such a program tended to be limited to use their files.

Some results pointed back to generally how-to articles, or excerpts missing good detail.

Creative search may find a few clues; proprietary software code where it exists, limits access.

Not sure what else to say. I've not a copy of my previous reply; so a bit of time is lost.

Had this site 'automatic' save done so, I'd not have wasted time, yet again. __it happens.

I've still got older Macs and likely have Roxio Toast on disc media; didn't use it all that much.

Sorry to not be of much help. This has been a waste of my effort & your time.

Good luck in any event!

Something I'd read suggested you can change the Roxio file end-name to .iso

and in past versions of OS X (and other software) had been able to copy them

more readily. (If to Copy - is different than - to Open & use.)

Is there a way to make us of the free open source Burn utility, if only duplicating

or copying your old image files to new media? Not sure if that'd solve any view

issues, given some aspect may not translate on the final end user experience.

A command line method had been discussed, on how to make the files work.

Converting to a more generic file type that keeps the content, is the path as

suggested by most.

Good luck in this matter!

PS: Not sure if this is helpful, the article is from 2008:

An old free app called "Burn" may be worth a try for opening Toast files. It runs in El Capitan, but I don't have any Toast files to test.

No PPC program runs in El Capitan

It's a "universal binary". OS 10.3.9 and up.
