Hi @Gangula,
I did a test on my side, and fields like {Path} seem to be invalid in Filter Query.
Using Filter array is a good choice, I have configured it based on what you provided.
In the condition of the Filter query, a judgment is added to check whether the item under this path is a folder. If it is a folder, it needs to be excluded.
Formula reference:
@and(equals(item()?['{Path}'], 'Copy/Test123/'),equals(item()?['{IsFolder}'], false))
Then use items(‘Apply_to_each’)[‘ {Identifier}’] in File to copy field to get the Id of the filtered files, then copy the file to the destination.

Please take a try.
Best Regards,
Barry
