copying a folder and its contents(subfolders and files) from one location to another

Hi Experts,

I'm trying to copy a folder containing several files and subfolders which also contain files and subfolders, etc... I don't know the names of the subfolders nor the files.

I would like to copy this main folder (c:\myfolder) to another location (c:\test\myfolder) with all its content. How do I achieve this. i havn't as yet found a way of copying a folder and its contents in java.

Thank you for your time,

thanks CEHJ. that was really helpfull but my environment takes the api as Runtime.getRuntime().exec("xcopy...

i have tried it with dir, mkdir which runs perfectly on the commandline but throws and exception as

CreateProcess: mkdir myfoldername error: 2

where mkdir myfoldername is a commandline command.

usign jbuilder 6 and tomcat 4.1.24

be most grateful to here from you.

why don't you try this:

public static void copyDirectory(File aSourceDirectory, File aDestinationDirectory) throws IOException {
int i;
File sourceFile;
File destinationFile;
File[] files = aSourceDirectory.listFiles();

if (!aDestinationDirectory.exists())
aDestinationDirectory.mkdirs();

for (i=0; i<files.length; i++) {
sourceFile = files[i];
destinationFile=new File(aDestinationDirectory, sourceFile.getName());
if (sourceFile.isDirectory()) {
if (!destinationFile.exists())
destinationFile.mkdir();
copyDirectory(sourceFile, destinationFile);
}
else {
copyFile(sourceFile, destinationFile);
}
}
}

cheers,
bruno
