Access Google Drive even when you're not connected to the Internet.
Internet outages and long plane rides shouldn't prevent you from working in Google Drive. Set up offline access so that the next time you're offline you'll still be able to view Google documents, spreadsheets, presentations, and drawings, shuffle folders around, and edit files stored in your Google Drive folder.
1) From drive.google.com in your Chrome browser, click More on the left-hand side of the screen.
2) Select Offline.
3) Setting up offline access is a two-step process. First, click the blue button that says Get the app. If you already have the app installed, skip to step 6.
4) You'll be taken to the Chrome web store. Click Add to Chrome in the upper-right corner of the browser window.
5) Once the app is installed, you'll be taken to a Chrome page with the Google Drive app icon. To return to Drive, click the Google Drive icon.
6) On the right side of the dialog on the Offline Docs page, click the blue button that says Enable Offline. At this point, it also works to click on the gear icon in the top-right corner of your main Drive view and select Enable Offline to set up offline access.
