Cannot delete folder using Java

Question

I am trying to delete a folder which has only files but no sub folders without success.

Code:

File rowFolder = new File(folderPath);
String[] files = r

You could be getting a failed delete for a number of reasons; the file could be locked by the file system, you may lack permissions, or could be open by another process etc.

If you're using Java 7 or above you can use the javax.nio.* API; it's a little more reliable & consistent than the legacy java.io.Fileclasses:

Path fp = file.toPath();
Files.delete(fp);

If you want to catch the possible exceptions:

try {
    Files.delete(path);
} catch (NoSuchFileException x) {
    System.err.format("%s: no such" + " file or directory%n", path);
} catch (DirectoryNotEmptyException x) {
    System.err.format("%s not empty%n", path);
} catch (IOException x) {
    // File permission problems are caught here.
    System.err.println(x);
}

Check the docs for more info on IO in Java 7
