The structure of microcomputer file systems

With an understanding of the structure of microcomputer file systems and what causes incompatibilities between them, it is possible to write software that will enable one system to read files written by another—provided they have physically compatible hardware.

File archival techniques using data compression

The performance of most small computer systems is determined, to a large extent, by the characteristics of their mass storage devices. Data compression can expand the storage capacity of such devices and also slightly increase their speed. Here, a summary of one method of data compression using Huffman variable length coding is presented, along with statistics of effectiveness for various file types and practical techniques for integrating such methods into a small computer system.
