FileReadBinary

Description

Reads an on-disk or in-memory binary file (such as an executable or image file) on the server, into a binary object parameter that you can use in the page. To send it through a web protocol (such as HTTP or SMTP) or store it in a database, first convert it to Base64 by using the ToBase64 function.

Note: This action reads the file into a variable in the local Variables scope. It is not intended for use with large files, such as logs, because they can bring down the server.

Returns

The entire contents of a binary file.
