Scanning file(s) by Windows Defender in command line

Hi!

I want to scan files/folders by Windows Defender in command line.
I copied whole help from command line to text file and tried it, but it scans anything other and I don't know what really.
I used command:

"C:\Program Files\Windows Defender\MpCmdRun.exe" -Scan -3 -File %path%

Where I'm not sure about scan argument - if is req'd to use the word "scan", and if, don't know if is req'd dash before scan type (normally it is not separate argument).
Also argument -File looks like not working.

Can anybody help me to fix it? And for to be sure add argument to see result to avoid else one mistake?

Thank you in advance.
Miro

Hi,

You can use the Start-MpScan PowerShell cmdlet to manually scan files with Windows Defender.
Then select what type of scan you want by defining the -ScanType switch. 

 Start-MpScan -ScanPath %path% -ScanType {QuickScan | FullScan | CustomScan}


Best regards,
Leon

Thanks, this method works and has an interactive progress bar.
The documentation provided here:

https://docs.microsoft.com/en-us/microsoft-365/security/defender-endpoint/command-line-arguments-microsoft-defender-antivirus?view=o365-worldwide

... for custom scans produces errors and the program path can change if the version is updated (don't want to update the path of the app every time it gets upgraded).

Martin.
