First Claim
1. A file system entity of a non-object oriented file system within a data processing system, said data processing system including storage media, wherein contents of said storage media are organized according to said non-object oriented file system, and wherein said data processing system executes an operating system, said file system entity comprising:
- data stored within said storage media;
a procedure stored within said storage media;
a node of said non-object oriented file system stored within said storage media, said node containing a plurality of attributes of said file system entity, said plurality of attributes including;
a data location indicator which indicates one or more locations of said data within said storage media;
a procedure location indicator which indicates one or more locations of portions of said procedure within said storage media; and
means for automatically invoking said procedure in response to said operating system accessing said node in order to access said data, wherein file system entity customization is enhanced.

Abstract
An improved file system, file system object and method for customizing a file system object within a data processing system are disclosed. The data processing system executes an operating system and includes a storage media having contents organized according to a file system. According to the present invention, a file system object is stored within the storage media which comprises object data, a procedure, and a node that contains a number of attributes of the file system object. The attributes of the file system object contained within the node include an object data location indicator which indicates one or more locations of the object data within the storage media and a procedure location indicator which indicates one or more locations of portions of the procedure within the storage media. In response to the operating system of the data processing system reading the node in order to access the object data of the file system object, execution of the procedure is automatically invoked, wherein functionality of the file system object is customized.
