GPG GUI is a front end for the symmetric passphrase feature of GnuPG. This means that any file, of any size, may be encrypted and protected with a password so that no other user can read the contents of the file. Folders cannot be encrypted or decrypted.
Basic usage for this application would be to get a copy of the file you want to protect, and then opening it with GPG GUI. Once the file is selected, the text entry area would be the place to specify a password the file will be encrypted with. Blank passwords will not work. Selecting "Encrypt" will start the short process that may take time depending on the size of the file. Once the process ends, the directory that the original file is in will have a duplicate protected copy, with the extention .gpg at the end.
