This app might be useful for you to send/receive files

When you need to transfer a file from your PC to your mobile or vice versa, no-signup
The big sell of Send Anywhere is that it uses P2P to transfer your files, without saving them on any server
along the way. So once the transfer is done, the file isn't going to be sitting on the cloud, waiting to be discovered
by someone else. Each file transfer is activated for a short time within which you can share its QR code or unique
6-digit key with someone else using either the Send Anywhere mobile app or the website. Any user can access this
file as long as they have the QR code or the unique key—there is no need to sign up for the app or web site.
