Have you forgotten to attach files in Gmail?
Gmail added a new feature that has come as a real blessing for anyone who sends attachments. This feature is available under Labs in Gmail.
I decided to give it a test and it still isn’t perfect. It still doesn’t work under all circumstances. The first time I tried it out, it did not work. The second time it did.
It throws up a popup window below, as you can see. You can always choose to send the message anyways. However, you can hit the Cancel button and then attach the file.
