Encryption of multiple files into another directory

[Josef Carnap]

Hello everyone,

GnuPG 2.0.29
Linux and Windows

by using the command

gpg2 --recipient 0x12345678 --encrypt-files /media/usb/folder_1/*

I can encrypt with a public key all files in the directory folder_1.

How can I encrypt alle the files in this directory to another directory
folder_2?

This command
 
gpg2 --output /media/usb/folder_2/ --recipient 0x12345678
--encrypt-files /media/usb/folder_1/*

does not work unfortunately. -- Any hints?

Best regards

Josef
