WinPT is just a frontend - it doesn't do anything that the command line can=
do. So by having command-line answers, you have WinPT answers. You need to=

If GnuPG can do it, so can WinPT. WinPT has no functionality of it's own, i=
just a facade. (Stop talking to the monkey and talk to the organ grinder!)

BTW the .gpg is a red herring. Any extension can be used, it's only Windows=
that puts sole trust in three characters and a dot. Linux and MacOS look at=
the content. To make things easier to understand, use the -a option to outp=
the signature or encrypted block as ASCII armour - it'll be easy to see tha=
the content is compatible.

Rubbish. Anyway, the configuration change is a once-only thing. I'm sure yo=
can manage to edit one text file.

Same thing, encrypting a file is still done using a client of some kind if =
prefer. Again, it's just a pretty box that asks GnuPG to do the work. For=20
this to work, GnuPG must be correctly configured and the pretty box knows=20
nothing about such details.

1. Post to the list, not to me.
2. It is clearly explained in the FAQ that GnuPG can be configured for full=
compatibility with PGP 5+ without affecting normal GnuPG performance.
3. You appear confused - there is no reason from what you've described to n=
use GnuPG / WinPT. It's only a simple change to a single text file.
4. There were presumably good reasons for choosing GnuPG over PGP in the fi=
place and those haven't changed.
5. Is editing a single config file too much to ask?
