I would say try the following :::

1. Put all files in one directory, say encrypted_files.

2. In the parent directory:

Cmdln> tar -covf - encrypted_files |gzip >encrypted_files.tar.gz
Cmdln> gpg -sear localid encrypted_files.tar.gz

3. And to decrypt (to test)

Cmdln> gpg -d encrypted_files.tar.gz.asc >decrypted
Cmdln> md5sum encrpted_files.tar.gz decrypted (or diff, to check whether
they match)

I say use any localid for which you have secret to test first this is
what i did doing
the above and it worked for me.
