Abstract
Improved techniques for providing users and application programs with access to data stored in computer systems are disclosed. The improved techniques are particularly well suited for use in computer systems where data can be logically organized in files presented in a file system. A multilevel caching system suitable for storing information relating to files in the file system is provided. The stored information can include file references suitable for locating files in the file system as well as other useful information about the file system. The multilevel caching system provides the ability to implement various caching strategies at different levels and increases the probability of cache hits when seeking to locate files in a file system. Accordingly, relatively expensive read operations to persistent storage devices can be minimized when locating files in the file system.
