Yes, but you're still imposing that on all the users for your
personal convenience!

Well yes, but why should the server have to do that for everybody
especially when you have to send the whole file over the network
before it can decide whether it wants it or not.

I'm not sure you should really be reading that much information
into the filename sent with a file upload anyway - it's really
more of a "suggested server filename" than necessarily the name
of the file on the client (though most if not all browsers do
just send the name of the local file).

I don't understand what uploading descriptions has to do with any
of this...
