The ANX Autoportal is basically a massive FTP application, supercharged.
When I joined ANX – the legacy application had about 300 users, most of which whom were using it to get CATIA hotfixes. They each had their own directory, and would each get a copy of the same hotfix (usually around 1-1.3 GB in size). This file would be copied to every directory of a user that needed it – often 20 or more.
What a waste of space!
