Vista - get file version information

So I want to find the version of a file in Powershell. How can I do this? I
don't see a fileversion property on the system.io.fileinfo object returned
from get-childitem.

get-childitem some_file|get-member

Then try:
(get-childitem some_file).VersionInfo

Or:
get-childitem some_file|foreach-object{$_.VersionInfo}

Try this:

ls $env:windir explorer.exe | % {$_.VersionInfo.FileVersion}

#...or
([System.Diagnostics.FileVersionInfo]::GetVersionInfo("$env:winDir\explorer.exe")).FileVersion

Didn't mean to intrude. Marco already answered, my post was too late, just ignore it. Thanks

answer that...

So your answer is better! ;-)

Hi Marco,

As an example, if I want to see the version on ntfs.sys I try:

(get-item 'c:\windows\system32\drivers\ntfs.sys').VersionInfo

It returns nothing for me. I tried what Kiron wrote too and no luck.

Hi Ryan,

Did you try the second part of what Kiron wrote? i.e.

[System.Diagnostics.FileVersionInfo]::GetVersionInfo('C:\Windows\System32\drivers\ntfs.sys').FileVersion

This is necessary because the version information is not included as a
member of the file objects in PowerShell.

If you're doing this for a lot of files, you could add it as a member for
all of them by doing this:

Get-ChildItem C:\Windows\System32\Drivers | Add-Member -Name
FileVersion -MemberType ScriptProperty -Value
{[System.Diagnostics.FileVersionInfo]::GetVersionInfo($this.FullName).FileVersion}
-PassThru | Format-Table -Property Name,FileVersion

e.g.

PS> (gcm powershell).FileVersionInfo.FileVersion
6.0.6000.16386 (winmain(wmbla).070112-1312)

Or if you have PSCX installed:

PS> Get-FileVersionInfo C:\Windows\system32\user32.dll

ProductVersion FileVersion FileName
-------------- ----------- --------
6.0.6000.16386 6.0.6000.1638... C:\Windows\system32\user32.dll
