I am newbie in this kindly help me out. Thanks.

Answer 1

@echo off
set directory=.
dir /s "%directory%" >"%temp%\filelist"
md5 "%temp%\filelist" >> output.txt
del/q "%temp%\filelist"

1. a recursive list of all files in the specified directory is written in a temporary file
   (use . for current directory, %~1 for the first command line parameter)
2. md5 hash of this file is appended to output.txt in current directory
3. the temporary file is deleted

Answer 2

The powershell way would be the following:

Get-ChildItem -Recurse . -File  | Get-FileHash -Algorithm MD5 | Format-Table -Wrap | Out-File -Append <File_Path>

or if you only want the file hashes:

Get-ChildItem -Recurse . -File | Get-FileHash -Algorithm MD5 | Select-Object Hash | Format-Table -HideTableHeaders  | Out-File -Append <File_Path>
