Admittedly I have not yet tried PGP, but have been using ccrypt (in the repos.) for some time to encrypt some folders/files. It is very easy to use. It overwrites the original files - there is no copy of the originals, but then one would have surely backed them up to DVD etc. (Apparently a feature to create a temorary file has been added). Encrypted files have the .cpt extension. Encryption is supposed to be strong, certainly good enough for my use. "Ccrypt uses strong 256-bit encryption which is currently considered to be unbreakable. Technically speaking, ccrypt uses the Rijndael block cipher. Rijndael was also chosen for the "Advanced Encryption Standard" (AES) by the U.S. government" See the website FAQ for all the details:- http://ccrypt.sourceforge.net/faq.html I have made a little animated gif to illustrate. No problems experienced after many encrypt/decrypt cycles.
