This document discusses file management in C programming. It defines a file as an object that stores data, information, settings or commands used with a computer program. There are two types of files - text files containing ASCII codes and binary files containing bytes. The main file operations are creating, opening, closing, reading and writing to files. To access files in a program, the FILE data type and pointer are used along with the fopen() function to open a file with a specified mode like read, write or append. Files must be closed using fclose() after operations are complete. The document provides details on file modes, defining and opening files.
