## Name

FREE — Display free space remaining on mass-storage device

## Synopsis

`free` `devname`

## Description

This command displays the number of unused 256-byte sectors on a device which are available for new files or for expanding existing files. The device name given must be that of a mass-storage multifile device. Free also displays the disk's name, creation date, and cluster size.

Data sectors are allocated in groups called “clusters”. The number of sectors per cluster depends on the storage capacity and physical characteristics of the specific device. This means that small amounts of free space may not be divisible into as many files. For example, if a given disk system uses 8 sectors per cluster, and a free command shows 32 sectors free, a maximum of four new files could be created even if each has only one cluster.

For more information see: the section called “Physical File Organization”
