Thanks to DoctorMos it is possible to mount google docs as a folder on your computer using gdocs mount GTK. Now instead of uploading your documents to google docs using a web browser, you can edit them in your favorite word processor and save them to a virtual drive in Nautilus. Any documents you save there will automatically show up in Google Docs, and you can drag any documents off of the drive to save them locally on your computer.
Install gdocs mount GTK in Ubuntu:
sudo add-apt-repository ppa:doctormo/ppa
sudo apt-get update && sudo aptitude install gdocs-mount-gtk
When installation is done, go to Applications > Accessories > Google Docs Connection to access the virtual drive
And add your google docs account
you will find all the files you have on your google docs account mounted to a virtual drive in your computer.
