Users of the Google Docs web service can easily access and manage their documents in one location online. However, they still would like to be able to back up and archive their files on their own systems. Unfortunately that isn’t so easy and requires you to download backups of each document individually.
How it works
Google Doc Download requires the Greasemonkey extension to be installed to work. Once installed here is what you see on your google documents control panel.
Just navigate to the document list that you wish to download and select the documents you want to download by clicking their checkboxes or click the select: all link at the bottom of the page. Click the drop down menu on the right side of the page that reads “Download Your Documents” and select a format. A new window will open and you now have a list of links to download all of the documents that you selected.
