How can I send more than 140mb folder to g mail account

you can't but if you Google File Flyer you can send files up to 5 gig I think it was last time I looked, you don't have to join or pay anything for it, just Google FileFlyer. And follow instructions. Just checked and at first you are limited to 400mb in one go x 3 but after you've sent one file the limit goes up, it uploads your files onto a server and sends an email message with a link for the recipient to go and download the files.

Just checked its only 140mb you want to send so you can do that in one first time.
Its fast too.
