Most of the Email services provides 20 MB of file attachment, Gmail the internet giant also provided 20 MB of attachment. Recently Google Operating System notified the increment in Gmail file attachment.

Gmail help confirms that Gmail file attachment extended to 25 MB. “With Gmail, you can send and receive messages up to 25 megabytes (MB) in size.
Please note that you may not be able to send larger attachments to contacts who use other email services with smaller attachment limits. If your attachment bounces, you should invite them to Gmail”.

You can upload 25 MB of multiple files from your Gmail account, but it’s a little bit tidious job and receiver should use Gmail, otherwise it’s diffcult to receive 25 MB of files.
