Bravenet File Upload Tutorial - 2
The next thing that happens is on your computer, not in your web browser. Clicking the Browse button opens up your File window for you to navigate to the file you want to upload.

Navigate to the folder on your computer where you have stored the file. You do remember where you saved it, don't you?

When you have clicked on the "Open" button in your File window it will close and you will be returned to your web page, only this time the file name you just selected will be showing in one of the upload slots ready to be uploaded.

When you have added your file click on the "upload file(s)" button.
After the file upload has completed you are returned to the File Manager page where all your files are listed.
When you are comfortable uploading one file at a time, you can start uploading more than one file at the same time - just fill in more slots in the Upload tool before clicking the Upload Files button.
