I tried to download Trezor Suite onto my Windows.
But I was told download Gpg4win.
I downloaded it and created OpenPGP pair.
Later I was told to sign and/or Encript.
To sign, I needed to select from a group of folder like 3D Objects, Contacts, WUB, KUB, Documents  Pictures, Downloads, Saved Games, KMS, Links, Quick Drive, Videos, Desktop , Pictures, Dekstop, Oracle_ire_usage, Music, Favorites, Searches, One Drive.
I don't know what to choose.
Have i gone into the wrong procedure? Do I really have to go to Gpg4win?
