Earlier today, John Siracusa released a Mac app called Hyperspace. The app scans any folder on your Mac, identifying duplicates. When the scan is finished, you can review the results and choose whether to reclaim the unnecessary space taken up by the duplicates.Ready to scan.Because of the way Apple’s APFS file system works on the Mac, Hyperspace’s deduplication of files doesn’t delete or move anything. How APFS does this is complicated and explained on the app’s website if you want to learn more, but to over-simplify a bit, APFS allows Hyperspace to eliminate duplicative data without changing the location of the files or their metadata. That means it’s a non-destructive operation, allowing you to reclaim drive space at no cost to your data’s integrity.Hyperspace gives you a chance to review the files it has identified as duplicates.The app has safety measures in place so system files aren’t affected, and users can label certain folders as ‘Source’ folders that will never be altered. You also have an opportunity to review the results of Hyperspace’s scan before the app does anything to your files.Hyperspace requires a subscription or one-time purchase to reclaim space.I took Hyperspace for a spin to see what it could find on my Mac Studio, which stores about 2.5 TB of data. The scan was impressively fast at around 30 seconds, identifying 4.04 GB of data that it could free up. That’s not a lot in the grand scheme of things, but it was also nice to know that I don’t generate a lot of duplicate files with my workflows.Hyperspace is free to download from the Mac App Store. The free version allows you to scan the folders on your system. However, to recover space, you need to subscribe for $9.99 per month or $19.99 per year, or purchase a lifetime license for $49.99.Access Extra Content and PerksFounded in 2015, Club MacStories has delivered exclusive content every week for nearly a decade.What started with weekly and monthly email newsletters has blossomed into a family of memberships designed every MacStories fan.Club MacStories: Weekly and monthly newsletters via email and the web that are brimming with apps, tips, automation workflows, longform writing, early access to the MacStories Unwind podcast, periodic giveaways, and more;Club MacStories+: Everything that Club MacStories offers, plus an active Discord community, advanced search and custom RSS features for exploring the Club’s entire back catalog, bonus columns, and dozens of app discounts;Club Premier: All of the above and AppStories+, an extended version of our flagship podcast that’s delivered early, ad-free, and in high-bitrate audio.Learn more here and from our Club FAQs.Join Now
