We are no longer making Quickoffice available for download. To work with Microsoft® Office files, install the newest versions of the Docs, Sheets, and Slides apps from Google Play on your Android phone or tablet, or the Docs, Sheets, and Slides apps from the App Store for your iPhone or iPad. Learn more about editing Office files in Google Docs, Sheets, and Slides.
If you're using a VPN or cloud storage account that cannot be added to Quickoffice, you may still be able to open, edit and save your documents. Most storage/VPN providers have an application that you can install on your phone or tablet that you can use to open files in Quickoffice.
If you open and edit files this way, you may need to save your changes to your device and upload the updated files separately.
