Files on a hard disk are NOT stored in memory. Files on a hard disk are stored on a hard disk.

You wrote "i know that file are stored in one or more than one clusters and information about the clusters and files are stored in File Allocation Table".

That is true of a hard disk with a FAT file system, but not for NTFS, ZFS, EXT-2, Reiser, etc.

Search on the Web for FAT file system documentation. On an MSDOS 2.11 floppy, for example, two copies of the FAT were kept in dedicated sectors.

Perhaps you want to use mmap() to map a file into main memory.

thanks for replay

you have wrote mmap()

but i have no idea about mmap()

please tell me somwthing about mmap()

is this a programming language function? if yes then from which language it belongs and how to use it..

waiting for your replay

thanks again

You can read about mmap() by googling it. It's a unix function, and if you use windows, you'll have to find the corresponding function that performs memory mapping.

Files on the hard disk is storted in Particular location where you can access the file by using Mmap().
