[RESOLVED] Adding characters to file name to prevent overwriting?

Time for you to look into recursion.

Public Function CheckAndGenerateUniqueCopyName(path As String, Optional seed As Integer = 1) As String
        'Check if the supplied path exists
        If System.IO.File.Exists(path) Then

           'The path exists so lets append the seed to the end of it
            path &= "(" & seed & ")"

            'Increment the seed value for the next iteration
            seed += 1
            
            'Call the same method with the new parameters until a result is found
            path = CheckAndGenerateUniqueCopyName(path, seed, False)
        End If

        Return path
    End Function

The above code has not been checked, but that is, in general, what you want to do.
