What happens if I have run out of space to send files for free?

If you are a registered user and have reached the space limit available for free mailings, you can switch to paid mailings, which provide 100GB of space. Or you can free up space by deleting files directly from the“Settings-” in your account under the section “Storage” provided that the recipient has not already made the download. Alternatively, you can wait for the files to expire, which will allow you to reset the storage and restore the available GB.
If you are an unregistered user, you will instead have to wait for the files to expire or choose to register with the app to get more free GB or switch to paid mailings.
