Duplicate For Mac

Duplicate is a minimalist and unobtrusive OS X system extension designed to improve the built-in copy and paste functions. The app integrates within the Finder contextual menu and seems to rely on the Mac Backup Guru app for the actual transfers.

The Duplicate app integrates with your system as an extension, which means that if you want to use it, you must open the System Preferences window and navigate to the Extensions tab to enable its functions.

At this point, within the Finder contextual menu you will be able to see the appropriate Duplicate Copy and Paste entries. The bad news is that you cannot activate them via hotkeys, so you must always go through the contextual menu.

This is the only way in which the Duplicate app makes it presence known: if you try to launch the app directly, you will only receive a message containing usage instructions.

Duplicate is able to copy and paste large folders up 10% faster than the Finder functions. At the same time, the copies are more accurate since the transfer will not fail even when dealing with a large amount of data, and you should not have any issues with permissions.

In fact, the exact copies created by Duplicated should be able to pass the Backup Bouncer test without any issues. What’s more, Duplicate can be used to replicate entire volumes.

Duplicate is an extension that integrates seamlessly in your system and enables you to duplicate large files, folders, and even volumes. The extension relies on the Mac Backup Guru OS X app, and can replicate the data without generating failed copies or permissions issues.
