Every Mac user knows about copy and paste, right? Command-C to copy. Command-V to paste. That keyboard combination works with text and graphics, but also with files. Go to the Finder, select a file, use Command-C to copy, then Command-V to paste. Voila. Instantly duplicated file.
Now try it with a Mac’s disk volume (no, don’t try it; just kidding).
Avengers Copy And Paste
Sure, copy and paste is valuable, built into almost every Mac app, the Finder, and behaviors are obvious. Copy this here, then paste it over there.
Duplicate is a free Mac utility which does copy and paste. Anything. Not just the standard copy and paste of text, graphics, photos, or spreadsheet information.
No, Duplicate can copy and past a folder with a gazillion* files inside (*slight exaggeration; haven’t tried the actual number of gazillion yet)– a simple way to duplicate a folder of files. A large folder of tiles. Copy. Then paste.
Big deal, right? Copy and paste.
Except Duplicate can copy and paste not only a large, multi-gigabyte folder full of files, it can also copy and and duplicate an entire Mac volume. And the copy passes the famed Backup Bouncer Test which determines copied file accuracy.
Think about this for a moment. You can copy and paste files from here to there (or make a side-by-side duplicate) right in the Finder already. Duplicate lets you do the same thing– with perfect copies– of multi-gigabyte folders full of files– from here to there.
And, you can copy and paste your Mac’s disk drive, from the Mac, to a freshly erased connected hard disk drive, and get a perfectly clone, bootable backup copy of the Mac.
Duplicate might be a strange way to do that kind of accurate copying but it works. The only feature I wish it had would turn it into a backup and sync app. Instead of just copying files from here to there, copy incrementally, which would speed up the process.
Otherwise, this is both strange and remarkable. Oh, and did I mention it’s free?
