How can you get the version information from a  dll or  exe file in PowerShell   I am specifically interested in File Version  though other version information  that is  Company  Language  Product Name  etc   would be helpful as well

Just another way to do it is to use the built-in file access technique    get-item   filename exe  VersionInfo   FL   You can also get any particular property off the VersionInfo  thus    get-item   filename exe  VersionInfo FileVersion   This is quite close to the dir technique

I prefer to install the PowerShell Community Extensions and just use the Get-FileVersionInfo function that it provides  Like so  Get-FileVersionInfo MyAssembly dll with output like   ProductVersion   FileVersion      FileName --------------   -----------      -------- 1 0 2907 18095   1 0 2907 18095   C  Path To MyAssembly dll  I ve used it against an entire directory of assemblies with great success

Nowadays you can get the FileVersionInfo from Get-Item or Get-ChildItem  but it will show the original FileVersion from the shipped product  and not the updated version  For instance    Get-Item C  Windows System32 Lsasrv dll  VersionInfo FileVersion   Interestingly  you can get the updated  patched  ProductVersion by using this    Get-Command C  Windows System32 Lsasrv dll  Version   The distinction I m making between  original  and  patched  is basically due to the way the FileVersion is calculated  see the docs here   Basically ever since Vista  the Windows API GetFileVersionInfo is querying part of the version information from the language neutral file  exe dll  and the non-fixed part from a language-specific mui file  which isn t updated every time the files change    So with a file like lsasrv  which got replaced due to security problems in SSL TLS RDS in November 2014  the versions reported by these two commands  at least for a while after that date  were different  and the second one is the more  correct  version    However  although it s correct in LSASrv  it s possible for the ProductVersion and FileVersion to be different  it s common  in fact   So the only way to get the updated Fileversion straight from the assembly file is to build it up yourself from the parts  something like this   Get-Item C  Windows System32 Lsasrv dll   ft FileName  File Part   Or by pulling the data from this    System Diagnostics FileVersionInfo   GetVersionInfo  this FullName    You can easily add this to all FileInfo objects by updating the TypeData in PowerShell   Update-TypeData -TypeName System IO FileInfo -MemberName FileVersion -MemberType ScriptProperty -Value       System Diagnostics FileVersionInfo   GetVersionInfo  this FullName               Version      FileMajorPart     FileMinorPart     FileBuildPart     FilePrivatePart -join               Now every time you do Get-ChildItem or Get-Item you ll have a FileVersion property that shows the updated FileVersion

As EBGreen said   System Diagnostics FileVersionInfo   GetVersionInfo path  will work  but remember that you can also get all the members of FileVersionInfo  for example    System Diagnostics FileVersionInfo   GetVersionInfo path  CompanyName   You should be able to use every member of FileVersionInfo documented here  which will get you basically anything you could ever want about the file

dir  is an alias for Get-ChildItem which will return back a System IO FileInfo class when you re calling it from the filesystem which has VersionInfo as a property  So       To get the version info of a single file do this   PS C  Windows gt   dir   write exe  VersionInfo   fl   OriginalFilename   write FileDescription    Windows Write ProductName        Microsoft   Windows   Operating System Comments           CompanyName        Microsoft Corporation FileName           C  Windows write exe FileVersion        6 1 7600 16385  win7 rtm 090713-1255  ProductVersion     6 1 7600 16385 IsDebug            False IsPatched          False IsPreRelease       False IsPrivateBuild     False IsSpecialBuild     False Language           English  United States  LegalCopyright        Microsoft Corporation  All rights reserved  LegalTrademarks    PrivateBuild       SpecialBuild         For multiple files this   PS C  Windows gt  dir   exe         VersionInfo    ProductVersion   FileVersion      FileName --------------   -----------      -------- 6 1 7600 16385   6 1 7600 1638    C  Windows bfsvc exe 6 1 7600 16385   6 1 7600 1638    C  Windows explorer exe 6 1 7600 16385   6 1 7600 1638    C  Windows fveupdate exe 6 1 7600 16385   6 1 7600 1638    C  Windows HelpPane exe 6 1 7600 16385   6 1 7600 1638    C  Windows hh exe 6 1 7600 16385   6 1 7600 1638    C  Windows notepad exe 6 1 7600 16385   6 1 7600 1638    C  Windows regedit exe 6 1 7600 16385   6 1 7600 1638    C  Windows splwow64 exe 1 7 0 0          1 7 0 0          C  Windows twunk 16 exe 1 7 1 0          1 7 1 0          C  Windows twunk 32 exe 6 1 7600 16385   6 1 7600 1638    C  Windows winhlp32 exe 6 1 7600 16385   6 1 7600 1638    C  Windows write exe

I find this useful   function Get-Version  filePath        name     Name  Name  Expression   split-path -leaf    FileName       path     Name  Path  Expression   split-path    FileName      dir -recurse -path  filePath       if     Name -match     dll   exe         VersionInfo     select FileVersion   name   path

I realise this has already been answered  but if anyone s interested in typing fewer characters  I believe this is the shortest way of writing this in PS v3    ls application exe     versioninfo    ls is an alias for Get-ChildItem   is an alias for ForEach-Object versioninfo here is a shorthand way of writing     VersionInfo    The benefit of using ls in this way is that you can easily adapt it to look for a given file within subfolders  For example  the following command will return version info for all files called application exe within subfolders   ls application exe -r     versioninfo    -r is an alias for -Recurse   You can further refine this by adding -ea silentlycontinue to ignore things like permission errors in folders you can t search   ls application exe -r -ea silentlycontinue     versioninfo    -ea is an alias for -ErrorAction   Finally  if you are getting ellipses       in your results  you can append   fl to return the information in a different format  This returns much more detail  although formatted in a list  rather that on one line per result   ls application exe -r -ea silentlycontinue     versioninfo   fl    fl is an alias for Format-List   I realise this is very similar to xcud s reply in that ls and dir are both aliases for Get-ChildItem  But I m hoping my  shortest  method will help someone   The final example could be written in long-hand in the following way   Get-ChildItem -Filter application exe -Recurse -ErrorAction SilentlyContinue   ForEach-Object     VersionInfo    Format-List       but I think my way is cooler and  for some  easier to remember   But mostly cooler

Since PowerShell can call  NET classes  you could do the following    System Diagnostics FileVersionInfo   GetVersionInfo  somefilepath   FileVersion   Or as noted here on a list of files   get-childitem   -include   dll   exe   foreach-object     0  t 1   -f    Name   System Diagnostics FileVersionInfo   GetVersionInfo     FileVersion     Or even nicer as a script  https   jtruher3 wordpress com 2006 05 14 powershell-and-file-version-information
