Encrypt Files and Folders with EFS in Windows 10  

This is a very old thread, but I'm hoping someone will see this and has an answer, because I've scoured the Internet and haven't been able to find it.

I have encrypted files on computer A using EFS. I sync those files with computer B using Syncthing. I have installed the EFS certificates from computer A onto computer B and both computers use Windows Pro and NTFS.

If I edit a file that was encrypted on computer A on computer B and save it, will it be encrypted with the original encryption certificate from computer A or with one from computer B? I'm hoping that the answer is "it's always re-encrypted with the same encryption credentials," because I edit files on both computer, but if not, does anyone know of another encryption program that is as flexible as EFS? I don't want to create separate containers I have to mount as drives, as with Veracrypt, if I don't have to.

Thank you! I'm currently unable to test this, and it's surprisingly hard to find this out online. After a fruitless search, I tried four AIs and three of them came to the opposite conclusion. They have a way to go before they can replace human expertise.

I don't think so. I had somewhat extensive "conversations" with two of them and described how I would export and import both certificates on both computers. I'm a Bard/Gemini tester, and I find that it is wrong about 50% of the time across a broad range of topics -- either completely wrong, or a mix of accurate and inaccurate. I follow up on where they've drawn their information from, if it's available, and they seem far too willing to make imaginative leaps to fill in information gaps instead of the more helpful "I don't know" or "it could be this or could be that."
