Gmail allows you to send attachments up to 25MB in size and receive files up to 50MB in size. When sending large files, it makes sense to use the built-in Google Drive. Click the Compose button in your Gmail account. At the bottom of the compose window, click the Google Drive button.
The window Insert files from Google Drive displays. Choose the files you'd like to attach. Decide how you wish to send the file at the bottom of the page: Any file stored in Drive can be linked, including files generated using Google Docs, Sheets, Slides, or Forms. Attachment only works with files created outside of Docs, Sheets, or Slides. After that, click Insert.
When you try to attach a file that is larger than 33MB, Outlook.com will invite you to upload it to your OneDrive account. The file is uploaded to the OneDrive Email attachments folder if you follow this prompt. Instead of receiving the file, the receiver will receive a link to it. A file from OneDrive can also be shared with a 2GB restriction.
Choose whether or not users can alter the file after it has been uploaded. Choose Change permissions and determine what to do with the file you just shared. There are two possibilities available to you.
Others who do not have access to your material can copy or download it without logging in.
Others in a shared folder have the ability to modify, add, and delete files.
