GPG Win and Decrypting multiple files

Forgive me if this is a simple question but it’s been bugging us for awhile. We are receiving multiple files daily that are all encrypted and need to be decrypted. THey all of the .gpg suffix. Is there a way using GPGwin that we can decrypt ALL files in the directory that end with .GPG? We don’t know the file names because they are based on the creation date and run down to the second.

Is this possible with the windows version?
