The Steganos Security Suite virtual secure drive (SLE) is a proprietary disk image format developed by Steganos Software GmbH for encrypted data storage. These files serve as virtual encrypted containers that appear as physical drives when mounted, allowing users to secure sensitive files and folders from unauthorized access. Although newer versions of the software favor the EDF format, SLE remains a recognizable legacy format for older encrypted volumes created within the Steganos ecosystem.
