Four little utilities now compatible with macOS Tahoes, covering repair of Finder aliases, creating test sparse files and checking special file types, looking up UTI types, and analysing language.
Sparsity
Sparse files are now common among databases, disk images, and virtual machines. How they work in APFS, how they’re created, and how they can explode.
Where are all those purgeable files? Two updated utilities to help you find them: Precize and Sparsity, which will crawl folders checking which files are purgeable, sparse or clones.
How APFS containers and volumes work. What hard links, clones and sparse files are, and when they break down.
Tired of HFS+? Disenchanted by APFS? Why not copy or back up to a different file system? Here are crocodiles waiting to bite you.
Sparse bundles, sparse files, and sparse matrices explained in a nutshell, and how a sparse bundle could have a band which is a sparse file containing a sparse matrix.
New version searches for sparse files and clones, reporting their individual sizes and totals for the folder or volume examined.
Can APFS really store more on disk using sparse files and clones? Is there such a thing as a free lunch, or do these tricks have a cost?
APFS can ‘clone’ files when copying or duplicating them within the same volume. But how can you tell whether any given file is a clone?
If there’s one thing we’re learning about APFS, it’s that file sizes are flexible. That means that free […]
