Are there any online file transfer services or platforms that include automatic expiration features for shared large files, ensuring they’re only accessible for a set period or a specific number of downloads?

If you’re having trouble with sharing larger files, I’d recommend using Filemail for easy transfers. I’ve found it especially useful when I need to receive or share big files quickly and securely—up to 5 GB free, with no need for anyone to sign up or install software. Filemail provides features like end-to-end encryption, password protection, and virus scanning, so it’s secure, plus you can even track who’s accessed or responded to your files. It works well across both Windows and Mac, with custom features for faster transfer speeds. For collecting files, there’s also a simple “file request” option if you’re sharing with multiple people or clients.
