GetRuntime().exec(cmd) createprocess error=2 when trying to copy

Question

Hi there,
Using .exe and copy methods have been covered quite allot in these forums, but I cant quite find one that shows me why this isnt working:
when I run the following code (on a windows machine)
String cmd="COPY \"" +origiFTPlocation+ "\\\\"+zipfilename+ "\" \""
+ finalLocation +  "\"";
try{
     Process run = Runtime.getRuntime().exec(cmd);
     run.waitFor();
     }catch(Exception e){System.out.print(e.getMessage());               
cmd = COPY "C:\\Documents and Settings\\psd_tmp4\\My Documents\\JavaProjX\\OWF\\origiFTPlocation\\age_v0_i0_ao.zip" "C:\\Documents and Settings\\psd_tmp4\\My Documents\\JavaProjX\\OWF\\finalLocation"I get the following error:
can not tun program "COPY": createprocess error=2, the sytem cannot find the file specified
but this works fine when copying and pasting into comand line???
I have tried converting to single slashes but get the same

Answer 1

I don't know much about DOS-ish commands, but presumably copy is not an executable program,
but rather the cmd.exe equivalent of what's called a "shell built-in" in unix. That is, I would guess that
the command "copy" is interpreted directly by cmd.exe.
If that's the case, I see the following options:
1) Execute cmd.exe and tell it to run the copy command. This probably has its own quirks that I'm not familiar with.
2) Find a copy executable somewhere on your system and invoke that (if it exists).
3) Create a .bat file that contains the copy command and execute that.
4) Do the file copy directly in Java, without invoking Runtime.exec.
