This page allows you to add new files to the File Storage section. As noted, individual files cannot be alrger than 2MB in size.
This page requires some knowledge of navigating your computer, since clicking the Browse or Choose File button (dependent on the web browser you are using) will open a new window, allowing you to navigate the folders on your compter, or other connected drive.
Once the file is selected, it's name will show up next to the Choose File / Browse button. Once this is complete, you can enter a short description of the file.
By default, the file will be added to the first folder that appears on the File Storage page, listed alphabetically. If you want the file to be stored in a different folder, simply use the drop-down menu to choose any other existing folder.
