I suspect there may be problems if the drive size is >2Tb as then it will no longer be a 32bit integer. (Adam: this doesn't seem right to me, though I'm not sure. 2^32 is about 4 GB's and I'm easily able to represent that large of a number returned from this. But if registers can hold > 32 bits then I don't know why there's System::Int64Op?)

== Description ==
'''Note:''' GetDiskFreeSpaceEx is not supported by the first edition of Windows 95.

Use GetDiskFreeSpace instead if you want your check to be compatible with this version.

This code is based on Sunjammer's code to [[CheckSpaceFree]], but uses the same system function call to return the drive capacity instead.

The value returned is the amount in KBytes.

== Notes ==
I suspect there may be problems if the drive size is >2Tb as then it will no longer be a 32bit integer.

Also on volumes with user quotas (ie NTFS servers) the amount may be less tham the actual amount - this warning is courtesy of the Microsoft documentation on the [http://msdn.microsoft.com/library/en-us/fileio/base/getdiskfreespaceex.asp GetDiskFreeSpaceEx] function.

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

; $1 - path to check (e.g. 'C:\') should work on \\computer\share\ also
; $1 - trashed returns vol space in KBytes
; (NB odd things may happen on >2Tb drives, have not checked)
function GetCapacityFunc
push $2
System::Call '${sysGetDiskFreeSpaceEx}(r1,.,.r2,)'
; convert the large integer byte values into managable kb
System::Int64Op $2 / 1024
Pop $1
Pop $2
