Of course! First of all we need a function that search for files.

Public Sub SearchFiles(ByVal Pattern As String, ByVal Path As String, ByVal FilesFound As ArrayList)
    FilesFound.AddRange(Directory.GetFiles(Path, Pattern))
End Sub

But where we should save the list of files? We can use a Array for it. Also we should define our output and input folder

Dim files As New ArrayList
Dim inDir As String = "input path"
Dim outDir As String = "output path"

We can now call this function like this:

SearchFiles("*.txt", inDir, files)

All .txt files in the folder are now saved in our Array List. But how we can work with it? We can now work with it like this:

Try
  For Each file As String In files
    Dim fName As String = Path.GetFileName(file)
    My.Computer.FileSystem.CopyFile(file , outDir & "\" & fName, overwrite:=False)
  Next
Catch ex As Exception
  Console.WriteLine(ex.ToString)
End Try

This will copy every .txt file that where found in our inDir to our outDir. If something goes wrong then you will see this in the console. Try it out and understand how it works :)
