Editors' note, February 1, 2015: Google has stopped supporting Quickoffice and has removed the app from the Google Play store. For alternative options, check out CNET's productivity suite software guide.
Acquired by Google in 2012, Quickoffice picks up where Google Drive falls short and lets you natively create and edit Microsoft Office files from your Android device. It doesn't require any converting to proprietary formats, and it can easily save your updated files to your Google Drive account in the cloud.
Still, while this recently updated app is adept at manipulating Word, Excel, and PowerPoint files, it still needs to learn a few tricks before it can be considered the go-to document editor on Android.
Moving and managing files
Quickoffice opens up to a nifty file manager that makes it easy to sift through your locally stored files, as well as those stored on your Google Drive account. For tablet users, this screen is especially nice, as it comes split into three panels and offers an efficient widescreen browsing experience.
From the file manager screen, you can create folders and organize your content, and all of your changes will automatically sync to Google Drive. You can even browse to a locally stored file on your device, and copy, cut, or share it to your account in the cloud.
To start editing, simply tap on one of your files onscreen, or hit the "+" button up top to create a new document.
The first thing you need to know about Quickoffice is that it is built to edit Microsoft Office files and not much else. This means you can use it for Word, Excel, and PowerPoint files, but not the Google Docs files that are stored on your Drive (though it can open Docs files as PDFs for viewing).
