Robert,
Thank you for your answer. It appears that, under BoxCrypter, plain text files do not exist for all encrypt/decrypt is dynamic.
This raises two further questions:
1. Is this practical for vary large files having sizes, for example, of 100MB or more? The encrypt/decrypt overhead would be vary large and tie up the computer, no?
2. Since a user never really has his file (plain text), if the password is lost or if the boxcryptor sw goes awry, then the information is lost forever, no?
Thanks for the answers.
