While I would like to give this software 4 stars, I can’t as the potential to be locked out of encrypted files is too great. I would love to see a portable version of this, so that I can back it up to an external drive. But if for whatever reason you lose access to your computer or hard drive, your files will be lost forever. Buying the non-free version may or may not fix this issue, but it’s not a chance I am willing to take.
