The SoftArtisans.FileUp object is the principal object used for all of SA-FileUp's functions including file upload, file download and database manipulation. It instanciates an internal dictionary object ("SoftArtisans.UploadDictionary"), as well as file objects for each uploaded file ("SoftArtisans.SAFile").
To use any upload or download function in SA-FileUp, you must first start by creating an instance of the SoftArtisans.SAFileUp object. To do this, you would use the ASP built-in Server.CreateObject function.
<% Set upl = Server.CreateObject("SoftArtisans.FileUp") %>
After that, all methods and properties are available to you.
