A stable internet connection isn’t always available, but sometimes work still needs to get done. Offline editing allows you to make changes to your files no matter what the state of your wireless. Google will sync any offline changes made as soon as a connection is found.
In order to use offline editing, you will need to have the Chrome browser, or a Chrome OS device. Start by downloading the Google Drive for your PC. The link can be found at the bottom of the Drive menu on the left. Follow the instructions to complete the installation.
To enable offline access on your computer, navigate to the My Drive main page. Click “More” on the left-hand side of the screen. Select “Offline Docs”, then click the “Enable offline” button.
You can also view non drive files such as PDFs, Microsoft Office files, and images, from your Google Drive folder, even when you're disconnected from the Internet.
