You can most certainly do what your asking with powershell as I do very similar myself using task scheduler. I’m not at my Pc can’t provide code but if you take a look at examples online searching for:
Get-Childitem filename filer
And
Move-Item
You should be able to do something like:
Get-childitem -path c:\someone\download -filter “ Dummy holdings*.xlsx” | Move-Item -Destination “c:\temp\copy\” -force
