INTRODUCTION

The Microsoft Compression Client Pack 1.0 for Microsoft Windows XP and Microsoft Windows Server 2003 contains the Msdelta.dll file. The Msdelta.dll file is a library that is part of the Windows Vista operating system. The Msdelta.dll file exports functionality to create and apply binary deltas. These deltas are used to efficiently download updates for Windows Vista. This advanced compression technology is also suitable for many other differential compression scenarios.

MORE INFORMATION

MSDelta is the next generation of the PatchAPI compression technology that was included in earlier version of the Windows operating system. MSDelta typically produces smaller deltas than PatchAPI.
