An extent is a contiguous area of storage in a computer file
system, reserved for a file. When a process requires
starting to write to a file, file-system management software
allocates a whole extent. When writing to the file again,
possibly after doing other write operations, the data
continues where the previous write left off. This reduces or
eliminates file fragmentation and possibly file scattering
too.(VISIT WWW.COOLINDIA.WEBS.COM FOR MORE)
