title: Splitting a file into several parts
body: <p>I'm trying to make a File copying application in Qt. I need to split the source file into several files so that my copy function can copy portions of data one by one and update the <code>QProgressBar</code>. To update the progress accurately I need to split the source file in 1% of its original size. Is my approach  wrong. I'm unable to find much resources on this topic.How can I split the source file into several parts of equal size?</p>
