Does File Upload use much server memory?
PowerWEB File Upload was designed to use very little server memory during a file upload operation. Typical HTTP file uploads using ASP.NET require the entire file get loaded into server memory before the page cycle is started. By default, File Upload is configured to stream files directly to disk, using only a small 50K memory buffer during the upload. However, if you choose to stream files to memory you can configure File Upload to do so. Using this method, you can periodically place uploaded bytes onto an open stream, effectively uploading file data from a client browser directly to a destination Stream object.
