=====Finding the free space on a disk=====

//by Richard Russell, October 2006//\\ \\  If you need to find out the amount of free space on a disk drive you can do that quite easily:\\ \\ 
<code bb4w>
        drive$ = "C:\"
        SYS "GetDiskFreeSpace", drive$, ^SpC%, ^BpS%, ^Free%, ^Total%
        gbytes_total = SpC% * BpS% * Total% / 2^30
        gbytes_free  = SpC% * BpS% * Free% / 2^30
</code>
This code fragment sets **gbytes_total** to the total capacity of the drive and **gbytes_free** to the free (unused) space on the drive, both in Gigabytes.\\ \\  If you only want to know the free space as a percentage of the total you don't need to calculate the values in Gbytes but simply use the **Free%** and **Total%** values:\\ \\ 
<code bb4w>
        PRINT "The disk has ";INT(100*Free%/Total%+0.5);"% free space"
