OpenAFS is the world's foremost location independent file system. With OpenAFS for Windows, users of Microsoft Windows 2000, XP, 2003, XP64, Vista (all editions), Server 2008 (all editions), Windows 7 (all editions) and Server 2008 R2 (all editions) can make the most of this proven data sharing solution. The OpenAFS Project provides binary installation packages appropriate for both individual users and organizations with thousands of members.

How to Decide Which Version to Install
The following guidelines should be used for choosing an installer type. If you are upgrading from a previous installation, select the same type of installer, EXE or MSI, as was previously installed on the system. If you are installing for the first time, choose the EXE if you are installing manually and the MSI if you either need to customize the installation package (via a transform) or wish to deploy via Active Directory Group Policy.

Each installer is provided in debug and non-debug versions. The debug versions should be installed only when you are experiencing a problem and you need to assist the OpenAFS developers in debugging the problem. The non-debug version is optimized for performance, does not generate logging information by default, and does not install symbol files.

Features:
1. Starting with the 1.5.50 release of OpenAFS for Windows, each of the AFS Client Service, the AFS Explorer Shell Extension, and the command-line tools are Unicode enabled. No longer is OpenAFS restricted to accessing file system objects whose names can be represented in the locale specific OEM code page. This has significant benefits for end users. Most importantly it permits non-Western languages to now be used for file system object names in AFS from Microsoft Windows operating systems. Now that Unicode names are supported, Roaming User Profiles and Folder Redirection will no longer fail when a user attempts to store an object with a name that cannot be represented in the OEM code page.
