Checking the version of a Dynamic Link Library (DLL) file

You can check version information for a Dynamic-link Library (DLL) file, i.e., a file with a .dll filename extension, or a executable file, i.e., a .exe file, from a command-line interface (CLI) on a Microsoft Windows system by using the Get-Item cmdlet. E.g.:

Learning Windows PowerShell
Learning Windows PowerShell

PS C:\> (Get-Item C:\Windows\explorer.exe).VersionInfo

ProductVersion   FileVersion      FileName
--------------   -----------      --------
10.0.15063.0     10.0.15063.0 ... C:\Windows\explorer.exe


PS C:\>

If you can't see all of the information, i.e., if you see three dots indicating that not all of the information is displayed, you can append | format-list to the command to have the output displayed in list format.

PS C:\> (Get-Item C:\Windows\explorer.exe).VersionInfo | format-list

If you don't see any ProductVersion or FileVersion information, using format-list may reveal some useful information, such as FileVersionRaw and ProductVersionRaw. E.g.:

PS C:\> (Get-Item "C:\program files (x86)\Graphics\Comic Life 3\ComicLife3.app\Contents\Windows\comiclife3.exe").VersionInfo

ProductVersion   FileVersion      FileName

PS C:\>

If there are spaces in the directory path or file name, you need to enclose the directory path and file name in double quotes as in the example above.

You can also retrieve just specific values, e.g., ProductVersion, CompanyName, LegalCopyright, etc., by putting a dot and then the value's name after VersionInfo. E.g.:

Udemy - April2516-25off-sitewide120x600
PS C:\> (Get-Item C:\Windows\explorer.exe).VersionInfo.ProductVersion
10.0.15063.0
PS C:\> (Get-Item C:\Windows\explorer.exe).VersionInfo.CompanyName
Microsoft Corporation
PS C:\> (Get-Item C:\Windows\explorer.exe).VersionInfo.LegalCopyright

PS C:\>

You can use the cmdlet with .dll as well as .exe files.

PS C:\> (Get-Item "C:\program files (x86)\Graphics\Comic Life 3\ComicLife3.app\Contents\Windows\libegl.dll").VersionInfo | format-list

If you wish to check values for multiple files at once, you can include wildcard characters, such as "*", in the file name and can also use a select statement to return specific values. E.g.:

PS C:\program files (x86)\graphics\Comic Life 3\ComicLife3.app\contents\windows> (Get-Item *.dll).VersionInfo | select Filename, ProductVersionRaw

FileName                                                                                          ProductVersionRaw
