Have some of your friends already attempted to send large files as email attachments to you? For example, files with interesting movies or a bunch of pictures from a birthday party. We know how frustrating it can be having to wait while all of those files are downloaded.
Moreover, email accounts have limits on attachment size. And you may not get all of the attached large files.
If your friend wants to send you large video files, it is best to use a file sharing service instead of attaching video directly to email. But first, the size of the video file needs to be checked. Some file sharing services have limits on the size of files to be uploaded.
Is the file too big? Don’t worry, there is still at least one service that lets you upload even as much as 1TB of data. It is FileWhopper. With FileWhopper, sending large files is easy and secure.

To prevent Mozilla Thunderbird from downloading large emails and attachments automatically, follow these steps:

  1. In the menu, find the “Edit Mail” option.
  2. Then go to “Newsgroup Account Settings”.
  3. If you have an IMAP account, go to the “Offline & Disk Space”, if it’s a POP account - go to “Disk Space”.
  4. Select “Do not download messages locally that are larger than __ KB”. And enter a maximum email size. For example, 50 KB.
  5. Save changes by clicking “OK”.

Important: if you have more than one email account, you need to go through the above steps for every one of your accounts.

After making all changes, Mozilla Thunderbird will not automatically download emails larger than the specified size. But if you like, you can still download the full message.
