FileUp version 4 is able to handle up to 4 gigabytes in both ASP and ASP.NET. It provides an ISAPI filter which circumvents the upload size limitation of ASP.NET and may improve performance of large uploads in ASP.   FileUp version 3.x and below is capable of processing uploads up to 2 gigabytes in size from ASP. However, when used within ASP.NET, very large uploads may not be possible with FileUp version 3.x and below, due to the limitations of ASP.NET, which caches the entire upload to memory before passing it to FileUp.

There are several server-side settings - Script Timeout, Session Timeout, Upload Read-ahead - that require adjustment to accommodate very large uploads. Instructions for adjusting these settings can be found here: http://support.softartisans.com/docs/FileUpV4/install_tailor.htm .

If you wish to upload files of unlimited size and number, FileUp Enterprise Edition provides that functionality.
