How to send large file through Yahoo Messenger

Dear Yahoo Support,
I always update Yahoo with latest version, I am wondering how to send/transfer large file to my friend by using Yahoo Messenger, usually drop of or corruption.
I have found a Plugin - Pando but it's not working well when I click to Send New nothing inside to fill in.

I dont care much about Plugin because not develope from yahoo. Please kindly to support with any way to send directly by yahoo messenger which I love this.

Thanks

Hoang
