problem merging files

[Rueben_Zero]

alright, i\'ve downloaded all five files, PSV0.2.010.Part1..Part1, all the way through part 5. then i downloaded the dos batch file \"run_me_first.bat\". however, when i go to run the batch file, this is what i get:
C:\\Planeshift>copy /b PSV0.2.010.Part1 + PSV0.2.010.Part2 + PSV0.2.010.Part3 + P
SV0.2.010.Part4 + PSV0.2.010.Part5 PlaneShiftV0.2.010.exe
        0 file(s) copied

now, by saying zero files copied, im assuming that something in the merging went incorrectly, but im confused as to what that would be. please help if you can.

fortunately, i have found the solution to my problem. all the files were incorrectly named when i had downloaded them, so the merging program didnt recognize them.
for instance, PSV0.2.010.Part1 was named PSV0.2.010.Part1..Part1.
sorry for the apparent waste of space.
