Reading all files in a directory including its sub directories

Question

This is how I set the path:

    dPath = dPath.replace("\\", "/");

    String iLen;
    String FileName;

    File iFolder = new File(dPath);
    File[] listOfFiles = iFolder.listFiles();

When searching:

    for (int i = 0; i < listOfFiles.length; i++) 
    {
        if (listOfFiles[i].isFile()) 
        {
            FileName = listOfFiles[i].getName();

            for(String s : iEndsWith)
            {
                if(FileName.toLowerCase().endsWith(s))
                {
                    SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yy h:mm aaa");
                    iLen = ReadableBytes(listOfFiles[i].length());

                    Object rowData[] = { FileName, listOfFiles[i].getAbsoluteFile(), sdf.format(listOfFiles[i].lastModified()), iLen };
                    iTableModel.addRow(rowData);

                    iTotalFiles ++;
                }
            }
        }
    }

That will only look for files in the given directory path, but not it's sub directories. How can I change that?

Answer 1

If you're on Java 7, you can use FileVisitor : http://docs.oracle.com/javase/tutorial/essential/io/walk.html

If not, just use a simple recursive version of your function.

Answer 2

您可以使用Apache Commons中的DirectoryWalker遍历目录层次结构。

Answer 3

Pass folder as Initial File which is to be searched

File foldr = new File("c:/javaFolder");

public void addFilesToList(File folder) {
        File[] listofFiles = folder.listFiles();
        if (listofFiles != null) {
            for (File file : listofFiles) {
                if (file.isFile()) {


                } else
                    addFilesToList(file);

            }
        }
    }
