Google has added some new helpful features to Google Docs.
Upload any file: You now have the ability to upload, store, and share any file in Google Docs. Your files will be stored in their original format(see note below) and accessible from anywhere/anytime with an internet connection. Note: When uploading files Google will ask if you want to convert to Google Docs format. If just want to store the file be sure to deselect this option when uploading.
Shared folders: In the past you could only share individual documents with others which could make sharing and collaborating very cumbersome. This new feature allows you to share an entire folder and it’s content with colleagues and/or students, saving everyone involved a lot of time.
Google has added other features and upgrades to their existing tools. Please visit http://www.google.com/google-d-s/whatsnew.html for more information.
