I’ve got a tablet with way more storage space than my phone. I’d like to be able to access all the files on it from my phone, just for viewing, without having to manually set up both devices for something cumbersome like TeamViewer. But also without having to use cloud storage. Is there any way to do this?
Solid Explorer allows you to turn on an FTP server. It’s not something you’d want to expose to the Internet or use long-term but it’s good for quick local transfers.
Cx File Explorer has a similar feature, along with a built-in FTP client. Another option would be to run an SSH server like SimpleSSHD on the device you want to share files from so you can access them via SFTP, which Cx File Explorer also supports. This permits more secure public key-based authentication rather than just a password.
