We need some simple customizations made to the open source FileZilla FTP client software for Windows. Basically, we want (1) a few menu items disabled, such as checking for updates, (2) disable access to any drive letter except C, and (3) disable the ability to open files from within FileZilla itself. In other words, we don't want people to be able to download a file such as an executable, and then click the executable from within FileZilla and launch the program.
The source code is available here: https://filezilla-project.org/sourcecode.php
We had this done once before several years ago and it cost us a few hundred dollars and now we need it to be done again.
