Copy, the cloud storage solution from Barracuda, just received what the developers call a "massive" update. The key feature is one that might not be immediately obvious: a totally rewritten sync engine, which promises to bring faster load times and more overall smoothness. If you update Copy and feel like everything is just working better, you can probably thank the new sync engine.

The other major addition is native PDF support, which gives it feature parity with competitors like Dropbox and Google Drive. By this I mean that the Copy app can open up your stored PDFs itself, rather than refer you to a third-party app. In many cases, if you don't have to read PDFs often, the only reader on your device could be Google Drive. If you're in the cloud storage business, you don't want your customers using a competitor just to look through basic documents if you can help it.

A nice detail that made its way into the update is that links to files in Copy now can open up in the app, instead of the web interface. Beyond that UX refinement, the developers also boast of many unspecified bug fixes, so we'll just have to take their word on that.

The app was not found in the store. :-(
