== Description ==
Based on the function [[CheckSpaceFree]] from [[sunjammer]] I created the following function which returns the free space (in kb) available for the path specified

== The Script ==
<highlight-nsis>OutFile "FreeSpace.exe"
!define sysGetDiskFreeSpaceEx 'kernel32::GetDiskFreeSpaceExA(t, *l, *l, *l) i'

; $0 - Path to check (can be a drive 'C:' or a full path 'C:\Windows')
; $1 - Return value, free space in kb

function FreeDiskSpace
System::Call '${sysGetDiskFreeSpaceEx}(r0,.,,.r1)'
; convert the large integer byte values into managable kb
System::Int64Op $1 / 1024
; Return the free space
Pop $1
functionend

section -
StrCpy $0 'C:\Windows' ; check how much free space is left for the path C:\Windows
Call FreeDiskSpace
MessageBox MB_OK "Free disk space in $0 : $1 kb"

StrCpy $2 12345 ; Free space required by you (in kb)
System::Int64Op $0 > $2 ; Compare the space required and the space available
Pop $3 ; Get the result ...

IntCmp $3 1 okay ; ... and compare it
MessageBox MB_OK "Error: Not enough disk space!"
okay:
MessageBox MB_OK "Enough disk space available!"
