When someone sends you the attachment in a Gmail message, you can download it to your computer. But you don’t always have to. Instead, you can preview various attachments, without leaving the Gmail environment.
Attachment preview feature in Gmail
You can view most attachments, including images, audio files, PDF- files, video clips, etc., Not taking up space on your computer. This feature is handy because there are many attachments that you don’t need to save. For example, if someone sends you a Word document they want you to read, you can simply view it right here and then reply to the email without downloading the file.
Email attachments are also easily integrated into Google Drive so if you don’t want the attachment to take up space on your hard drive, you can save it directly to your Google account. This feature allows you to delete an email but still view the attachment anytime, anywhere.
Some file types cannot be viewed in Gmail, including files ISO and RAR .
