How do I upload files?
To the right of the folder you want to upload the file, from the Add drop-down menu, select Upload file.
This displays the Upload Files page.
By default, the Display Name is the same as the file name. You can edit the Display name here.
Note: The selected file name will appear to the right of the Browse button.
You can upload as many files as you want (within the site's uploading size limit) by clicking Add Another File.
