System.callSystem with xcopy

Question

Hey guys,
I'm trying to copy a directory from one location to another using system.callSystem with the command xcopy. I've tested the string that I'm using as the parameter directly in the command prompt and it works, so I know that I'm feeding the function correctly. However, when I run it, nothing happens. Any ideas what could be going wrong? Is there something I'm missing?
here's the call:
system.callSystem('xcopy "' + sourceDir + '\\*.*" /e "' + targetDir + '"');
that string I'm feeding it is the equivalent of
xcopy "\\SOURCE_NETWORK\SOURCE_DIRECTORY\*.*" /e "\\TARGET_NETWORK\TARGET_DIRECTORY"

I test you code in AE CC 2014 ,and failed too. Maybe scripts do not have Direct permission to xcopy.Try the following method.
callStr = 'xcopy "' + sourceDir + '\\*.*" /e "' + targetDir + '"';
system.callSystem("cmd.exe /c \""+callStr+"\"");
It works fine now.So system.callSystem() does not equal to cmd.exe actually.  You should call the cmd.exe in this method.
However, at least  we can directly use "explorer" to approach the same goal.Just save the command string as a *cmd file.After running the temp file by call "explorer",remove it.
Here is the code:
callStr = 'xcopy "' + sourceDir + '\\*.*" /e "' + targetDir + '"';
outFile = File("~/Desktop/tempCmd.cmd");
outFile.open("w");
outFile.write(callStr);
outFile.close();
system.callSystem("explorer " + outFile.fsName.toString());
outFile.remove();
The difference of the two methods exists.The first method does show the String you called in cmd interface,while the second method not.
By the way,it seems that Relative Path does not work with xcopy,so make sure you convert the souceDir and targetDir to Absolute Path.
