hex editing multiple files

[SuperFlomm]

Code:

Get-ChildItem "C:\MyFiles" -Filter *.XA | `
Foreach-Object{
   $bytes = [System.IO.File]::ReadAllBytes($_.FullName);
   $bytes[2] = 0x4A;
   
   [System.IO.File]::WriteAllBytes("C:\MyFiles\" + $_.BaseName + ".XA", $bytes);
}

Thank you! This works beautifully. Good Job.
A small bug though: the .txt in the first line has to be .XA
