When logged into their WebShuttle account, a user can click on the Filemenu in the upper, left-hand corner of their screen, and then select Upload File from the menu that appears. This will bring up WebShuttle's Upload Dictation File screen.
On the Upload Dictation File screen, click on the button labeled Browse.... This will open the standard Choose File window. Navigate in this window to find the file you want to upload, select that file, then click the Open button to return to the WebShuttle screen. The file you selected should be listed in the first box, labeled File.
Once the file is selected, click the button labeled Upload File. A box will pop up telling you that the file was successfully uploaded.
