Batch Upload Files to Google Docs

You'd think that Google considered Docs & Spreadsheets
important enough to make it easy to import files. Or to export files.
You can do that one file at a time, but it becomes tiresome if you have
a lot of files.

Fortunately, the latest version of Google Toolbar for Firefox
has a feature that lets you drag and drop files to your browser and
they are automatically uploaded to Google Docs. To upload more files at
a time, go to Windows Explorer or other file manager, select your files
and drag them in Firefox.

To activate the feature, to go to
Google Docs & Spreadsheets after installing the toolbar. You'll get
a prompt that asks you if you want to enable the feature.
Alternatively, click on Settings / Options and enable "Docs &
Spreadsheets".
