3.1 SecureDELTA output files


  Contents:


During the binary diff file creation process we call SecureENCODING, SecureDELTA APP creates two types of files:


1. SecureUPDATE binary diff file:


This file is output on the Encode page. Applying the secure encoding (SecureENCODING) over Source and Target files results in a binary delta file to which a ".SecureDELTA" or ".XtremeDELTA" filename extension is applied.

Please note, this is not a SecureSFX (secure self-eXtracting file). It only the payload needed by SecureSFX, which contains the headers and the set of commands and the binary data (payload) needed to reconstruct on a remove location a bit-by-bit identical target file


2. SecureSFX file:


This file is output on the Installer page. SecureDELTA application outputs a SFX (Self-eXtracting Stub Installer, or SecureDELTA Installer), we also call the SecurePATCH™ file.

When launched remotely on your client's pc, it will use the source file located within the same folder, to output a target file, bit-by-bit identical with the target file it was created against in the SecureENCODING process.


During the SecureENCODING process, the old file will be renamed with a ".backup" filename extension.
