Here's how you can upload multiple files to Google Docs:
- Click the Upload button on the Docs list homepage.

- Click Select files to upload files from your computer. When the Browse dialog is open, press Shift and click the files you'd like to upload to Google Docs. Alternatively, click the Select more files link that appears after you upload the first file.
- Pick a folder to which you'd like to upload the files (this is optional), and click the Start upload button.

Your uploaded files will be converted to Google Docs format. Read on the file-size limits for uploading to Google Docs.
You can also upload multiple files to Google Docs by using the Google Docs List Data API. It allows client applications to upload documents to Google Docs and list them in the form of Google Data API ("GData") feeds. Learn more about the Google Documents List Data API.
