What is the best way to copy files out of a 140 GB dmg file from an external USB drive that is a backup from a previous Mac?

It seems to take way too long to copy the whole entire dmg. Trying to mount it has issues as the file is really big. All I want is to extract out a couple of folders from the dmg.
Is there anyway to deal with dmg files at a much more detailed level? Also there is a chance that the dmg file is corrupted, however doing a Disk Utility Verify Disk shows that the volume is OK.
So I'm not sure how to deal with this file as I'm not sure if it's worth waiting for the entire thing to copy (9 hours to copy) to know if I will be able to mount it once it's copied over. Is there a way I can deal with large dmg files in a much more efficient manner?
