PGP disk image (PGD) is a proprietary encrypted container format originally developed by PGP Corporation for secure data storage and transport. It is primarily used to create virtual encrypted volumes that mount as local drives within the PGP Desktop software suite for transparent file encryption. Now considered a legacy format, it has largely been superseded by modern full-disk encryption solutions following the acquisition of the company by Symantec.
