Syntax:
${GetSize} "[Drive]" "[Options]" $var

"[Drive]" ; Disk to check
;
"[Options]" ; /D=[T|O|F]
; /D=T - Total space (default)
; /D=O - Occupied space
; /D=F - Free space
; /S=[B|K|M|G]
; /S=B - size in Bytes (default)
; /S=K - size in Kilobytes
; /S=M - size in Megabytes
; /S=G - size in Gigabytes
;
$var ; Result: Size

Note:
-Error flag if disk isn't exist or not ready
-Error flag if syntax error

Example:
Section
${DriveSpace} "C:\" "/D=F /S=M" $R0
; $R0="2530" megabytes free on drive C:
