files109

A files system demonstration for linux.

This files system is aimed at supporting unlimited files. The number of files here is dependent on the size of the files system.

Brief Description

The files system is divided into two parts: indexes and data part

Indexes Part

The indexes part looks like this for example:

===BEGIN===
data_key: james.txt
data_begin: 10
data_end: 109

data_key: jame1.txt
data_begin: 110
data_end: 137

data_key: jame2.txt
data_begin: 138
data_end: 142

===END===

The Indexes part is written to the end of the partition.

It is used to get the file contents from the data part.

Data Part

The data part has no file structure. It is written at the beginning of the partition
