What do you do when you need to send a file to someone you don’t interact with a lot?
Many of us use email attachments for small files because it’s quick and easy to share modest amounts of data that way.
Sure, the attachment will probably lie around in the recipient’s mailbox for days or months, or even years, which might not be quite what you had in mind…
…but when you send someone else a file, you can’t control what they do with it anyway, or how long they keep it, or how widely visible it is on their corporate network after they save it.
But email is no good for large files such as audio data or videos because most email servers quite reasonably have a low limit on message sizes to stop the system from getting clogged up by attachments.
So the usual fallback for sending files that you can’t or don’t want to transmit via email is to use a file sharing service instead, which is rather like using webmail, only without the messaging part.
You upload the file to a file-sharing site, optionally setting various options that describe which other users can see it, and for how long, and then send the recipient an email that contains a download link where they can fetch the file at their leisure.
