Encryption for the Masses (E4M) is a free disk encryption software for Windows NT/9x/Me. E4M is no longer maintained; its author, Paul Le Roux, joined Shaun Hollingworth (the author of the Scramdisk) to produce E4M's commercial successor, DriveCrypt.
TrueCrypt was based on E4M's source code.[1] Truecrypt uses a different container format than E4M, which makes it impossible to use one of these programs to access an encrypted volume created by the other.
