I feel like an idiot - I can't figure this one out.
I'm extremely new to Powershell, and even scripting in general.

I can't figure out how to do this:



$pct = $DiskDrive.FreeSpace /= $DiskDrive.Size
It doesn't work as / either.

The operation '[System.UInt64] /= [System.UInt64]' is not defined.
At C:\powershell\Test Scripts\freespace2.ps1:7 char:31
+ $pct = $DiskDrive.FreeSpace /= <<<< $DiskDrive.Size

From what I can tell /= will divide the objects' values.
Am I using this incorrectly? I just want a percentage of freespace

Thanks!!

Hey,

Use / instead, not /=. The latter is a combined divide-and-assign
operator, much like +=, -= and *=. The latter is used like:

instead of:

$x = 10
$x = $x / 2

use:

$x = 10
$x /= 2

So effectively saving yourself the extra typing.

It's a bug that will be fixed in v2. To work around it cast either, or both, [uInt64] to [long], [decimal], [single] or [double]:

$DiskDrive = gwmi win32_logicaldisk -f "Name='c:'"
$DiskDrive.FreeSpace / [long]$DiskDrive.Size
[long]$DiskDrive.FreeSpace / $DiskDrive.Size
[long]$DiskDrive.FreeSpace / [long]$DiskDrive.Size

Thank you!
The [long] is exactly what I needed.
