Offline Google Drive
Google Drive is a nice web-based file storage with office suites feature. Just in case you don’t know how to make it available offline, here is how:
Go to drive.google.com in Chrome web browser (Offline mode only available in Chrome). Login to your Google account if you haven’t. Then click “More” and select “Offline”. The sync process will begin automagically. This may takes a while. You must have at least one saved document stored in Google Drive to use offline mode. After Google Drive is finished syncing, you can now access your documents offline. To access them you still need Chrome and head to drive.google.com. If internet connection unavailable, Chrome will activate the offline mode. Any changes you make to documents while you are offline will be synced the next time you’re online and vice versa.
Where are the files?
Win7: C:\Users\<username>\AppData\Local\Google\Chrome\User Data\Default\IndexedDB\
Mac: I don’t know.
They can only be read with Chrome as I understand it. If you want a more traditional style folder access and local versions of your files, the Google Drive app (Windows and Mac only) makes it a little easier to access your files from your desktop.
My biggest gripe with offline mode is that some features aren’t available offline (like the detail view, ‘download as’ etc).
