How to protect collections of files using different encryption passwords, and making most efficient use of storage space.

So how can a VM of 119.6 GB fit in a 100 GB container? How sparse files can make VMs and disk images smaller on disk.
Details of the three standard Cryptexes in Ventura 13.3, when they can be loaded in the boot process, and where they fit in with Rapid Security Responses.
How APFS can trim free space in a read/write disk image and transform it into a sparse file, so it uses storage more efficiently.
Plain read/write (UDRW), sparse image (UDSP), and sparse bundle (UDSB) compared for storage efficiency, performance, and convenience.
All you need to know about the sparse RAW disk images used inside lightweight VMs on Apple silicon Macs.
In Monterey and Ventura, regular read-write UDRW disk images can now be APFS sparse files, and work more efficiently than sparse images or sparse bundles.
Disk images originated in the 1960s, and are still valuable tools in modern macOS. They have their limitations, though, and in some cases should be replaced by APFS volumes.
Virtual Machines for lightweight virtualisation on Apple silicon Macs rely on sparse files. Here are tips to ensure they stay small and don’t explode to full size.
Download some vital free software, mount its disk image, run the Installer package there – but why does Ventura refuse to install it, and what you do?
