Gmail has increased the size of the attachment from 20 to 25 MB

Now you can exchange letters with attachments up to 25 MB.
The problem is that the Gmailov flash uploader sometimes does not allow uploading files of more than 10 MB and gives an error. This problem at the moment can be circumvented by switching to the standard uploader in the Gmail settings.

And naturally, the recipient's client should support large investments, which, however, is an additional incentive to switch to Gmail :)
