File System Classes
Introduction
Classes in this group let you work with things such as ordered collections of associations of keys and values, fixed length blocks to and from an associated RWFile, page heaps, encapsulated binary file operations, and disk allocation.
Table 20 lists the File System Classes. This chapter provides information on using some of these classes; the SourcePro API Reference Guide provides detailed information on each class in this class group.
