change extension and move file, using

I have the following code, which changes the extension of a txt to doc, and then moves it (from d:\1 to d:\2). The extension changes successfully, but it does not move, and I get an error

Cannot create a file when that file already exists.

Please suggest.

For Each filePath In Directory.GetFiles("D:\1", "*.txt")
File.Move(filePath, Path.ChangeExtension(filePath, ".doc"))
Dim filesToMove = From f In New DirectoryInfo("d:\1").EnumerateFiles("*.doc")
For Each f In filesToMove

This will check for an existing file of the same name and delete it first (you may want to handle this differently). It will then move and rename in one call to File.Move

Dim directory1 = "D:\1"
Dim directory2 = "D:\2"
For Each oldFileName In Directory.GetFiles(directory1, "*.txt")
    Dim newFileName = Path.ChangeExtension(oldFileName, ".doc").Replace(directory1, directory2)
    If File.Exists(newFileName) Then File.Delete(newFileName)
    File.Move(oldFileName, newFileName)
