Introduction
Prior to
Version 8, the Flash Player did not support any mechanism for
allowing the user to browse her computer for files. Furthermore,
Flash Player didn't have a mechanism for uploading or downloading
files, either. As such, most web applications used HTML-based
solutions for uploading and downloading files. Flash-based
applications not deployed on the Web often had to use customized
solutions for uploading and downloading files. Flash Player 8 and
higher now supports the new APIs, which greatly simplify file I/O
by allowing Flash Player to browse a user's system for files to
upload and download.
Flash Player allows users to browse to files on
their local disks and upload and download files using the
FileReference and FileReferenceList classes. This
chapter discusses the details of working with those APIs.
