Keep a working folder aligned between your laptop and desktop without making a central cloud drive the home of those files. Useful for repeated changes, rather than sending each file again.

Install on two computers you control, approve their device identities and share a test folder containing copies. Verify a small change reaches the other computer before adding important work.
