Windows equivalent of whereis?

"The where command does what you want and goes back at least to the resource kit for Windows 98, and is included by default in Server 2003, Vista, and newer:

C:\>where csc
C:\Windows\Microsoft.NET\Framework\v3.5\csc.exe
C:\Windows\Microsoft.NET\Framework\v2.0.50727\csc.exe

If executed with no arguments (on Vista), it results in one of my favorite messages:

C:\>where
ERROR: The operation completed successfully.

If executing in PowerShell, be sure to include '.exe' to distinguish from any 'where' aliases or scripts along the path. ('where' is a typical alias for Where-Object.ps1)

C:\> where.exe where.exe
C:\Windows\System32\where.exe"

"hackerish which.cmd:

@echo off
@set PATH=.;%PATH%

@rem
@rem about: something similar like the unix-alike-which, but with
@rem within pure cmd
@rem

if ""%1"" == """" (
@echo Usage:
@echo.
@echo which 'cmd'
@echo.
@echo.if 'cmd' is not found, ERRORLEVEL is set to 1
@echo.
) else (
( @for %%f in (%1 %1.exe %1.cmd %1.bat %1.pif) do if not ""%%~$PATH:f"" == """" ( @echo %%~$PATH:f ) else @set ERRORLEVEL=1)
)"

"I was searching for this today and since I'm on XP without the resource kit, I turned to powershell with the following command:

dir -path c:\ -filter ffmpeg.* -r"

"function find ($string) {
Get-ChildItem -Path 'c:\' -Recurse -Filter $string;
}

function whereis ($string) {
$superpath = ""$env:Path;C:\Program Files;C:\Program Files (x86)"";
(echo $superpath).Split(';') | Get-ChildItem -Recurse -Filter $string;
}

Example:

PS >find Mozilla.admx

Directory: C:\Windows\PolicyDefinitions

Mode LastWriteTime Length Name
---- ------------- ------ ----
-a---- 1/27/2016 12:22 PM 37146 Mozilla.admx

PS >whereis firefox.exe

Directory: C:\Program Files\Mozilla Firefox

Mode LastWriteTime Length Name
---- ------------- ------ ----
-a---- 9/21/2017 5:30 PM 477136 firefox.exe"

"Using the where command on windows 10, in cmd, I used the following command to recursively search c drive for copies of the c# compiler, csc.exe.

c:\> where /r c:\ csc.exe

Sample:
using where to find all copies of csc.exe"
