Is there an operation to move and overwrite files?

Question

I am looking for an operation to move and overwrite a File. I know that there is a new Method in Java7, but I was hoping to get around Java7. Also I know about the Methods in FileUtils and Guava, but the FileUtils won't overwrite and the Guava one does not document it.

Also I am aware, I could write my own Method, well I started, but saw some Problems here and there, so I was hoping for something already done.

Do you have any suggestions?

Answer 1

I use the following method:

public static void rename(String oldFileName, String newFileName) {
    new File(newFileName).delete();
    File oldFile = new File(oldFileName);
    oldFile.renameTo(new File(newFileName));
}

Apache FileUtils JavaDoc for FileUtils.copyFileToDirectory says, "If the destination file exists, then this method will overwrite it." After the copy, you could verify before deleting.

public boolean moveFile(File origfile, File destfile)
{
    boolean fileMoved = false;
    try{
    FileUtils.copyFileToDirectory(origfile,new File(destfile.getParent()),true);
    File newfile = new File(destfile.getParent() + File.separator + origfile.getName());
    if(newfile.exists() && FileUtils.contentEqualsIgnoreCaseEOL(origfile,newfile,"UTF-8"))
    {
        origfile.delete();
        fileMoved = true;
    }
    else
    {
        System.out.println("File fail to move successfully!");
    }
    }catch(Exception e){System.out.println(e);}
    return fileMoved;
}
