I would like to copy a file from one directory to another using Java and the FileUtils classes of apache org commons.

I wrote up a quick java program to test on my local system. Here is the code. The file exists, but the copying of the file to another directory isn't working. What am I missing? Is there some improper syntax somewhere?

import org.apache.commons.io.FileUtils;
import java.io.File;

class MoveFile {

    public static void main(String[] args) {
        MoveFile myobj = new MoveFile();
        myobj.moveTheFile();
    }

    public void moveTheFile () {
        try {
            File destDir = new File("C:\\Folder1\\temp2");
            File srcFile = new File("C:\\Folder1\\temp\\card.png");
            FileUtils.copyFileToDirectory(srcFile, destDir);
        } catch(Exception e) {
        }
    }

}

Replicated your error and it only fails when the program does not have permission to write on destination folder. Even catching a throwable and printing stacktrace shows no info and the method is quite silent... if the folder does not exist, the method creates it so disregard that possible correction.

Check write permissions in destination folder
