    how to create PFX file to export EFS files


    I'm embarrassed to admit that with aging, I seem to be forgetting some things that used to be easy. I need help!

    I have a home laptop with Windows 10 Pro, ver 22h2. It has a folder on D: called DOCS that is EFS encrypted. I also have there a PFX file from 2019. I must have created it after I bought this laptop that year, or I copied it from my previous laptop. I tested that file on a different computer. I copied some EFS encrypted files to a separate laptop. Couldn't read/access them. Then I imported the old PFX file and then could read those encrypted files. So I guess this means the old PFX file is still working.

    Now I'm preparing to receive a new laptop with Windows 11 Pro. I'd like to create a new PFX file on my current laptop to import on the new laptop, but I have forgotten how I did it before. (If that is even necessary.) I've searched online but run into issues of having to get a "certification authority" (?) from some server that I know nothing about. I have no corporate network, just home.

    I have forgotten how to create a PFX file so I can transfer EFS encrypted files to a new PC. I prefer not to decrypt them all (over 50 GB) before transferring. All I can remember is that before when I did this, it was relatively simple and quick.

    Can someone please help me with simple directions or a link to same? The Microsoft link I found is way too complicated and talks about the"certification authority".

    Thank you, spunk. The link you gave is for importing the cert & key. What I'm looking for is how to export the cert and key, that is, to create a new PFX file. But maybe my old one is sufficient, as I described in my OP?

    You would import your existing EFS and PFX files into your new PC
