Preventing file from being overwiten

[MobilAdmin]

I have a script that will move and rename a file into a different folder, then create a new file. The script works fine. When I run the script again the moved file stays the same, but the file I created gets erased. Even if there is new data in the created file. My goal is to prevent the script from creating the new file if the file that is being moved and rename already exists. This is what I have so far...

#include <File.au3>

Local $file, $rename, $renfile, $filemake

$file = FileGetTime("C:\Test1\test.txt")

$date = $file[1] & $file[2] & $file[0]

$renfile = FileMove("C:\Test1\test.txt", "C:\Test2\test" & $date & ".txt")

$filemake = _FileCreate("C:\Test1\test.txt")

Any ideas would be helpful. Thanks
