Ext File Specs, Overview
*Conan The Librarian
Extended File Specifications includes support for the following: o The ODS-5 disk structure. ODS-5 is an extension to the existing ODS-2 disk structure, and adds the ability to use extended file names that can be more easily mapped between Windows and OpenVMS. ODS-5 expands the available character set and filename length to be consistent with Windows 95 and Windows NT, and sets the stage for future Unicode file name support through PATHWORKS. o Deeper directories. Enhancements to RMS provide deep directory support on both ODS-2 and ODS-5 volumes. Taken together, these components provide much greater flexibility for OpenVMS Alpha systems (using Advanced Server for OpenVMS 7.2, formerly known as PATHWORKS for OpenVMS), to store, manage, serve, and access files that have names similar to those in a Windows 95 or Windows NT environment. This topic provides an overview of the benefits, features, and support for Extended File Specifications, as well as changes in OpenVMS behavior that occur when using Extended File Specifications.
