    Post Hi I am developing spring-quartz filewatcher concept.my scheduler will run every 5 minutes.when a large file is came in to our directory how would i know whethe a file will fully copied or not

    This is my filewatcher code:


    Path myDir = Paths.get("D:/data");

    try {
    System.out.println(" task started:"+new Date());
    WatchService watcher = myDir.getFileSystem().newWatchService();
    myDir.register(watcher, StandardWatchEventKinds.ENTRY_CREATE,
    StandardWatchEventKinds.ENTRY_DELETE, StandardWatchEventKinds.ENTRY_MODIFY);

    WatchKey watckKey = watcher.take();

    List<WatchEvent<?>> events = watckKey.pollEvents();
    for (WatchEvent event : events) {
    if (event.kind() == StandardWatchEventKinds.ENTRY_CREATE) {
    System.out.println("Created: " + event.context().toString());
    }
    if (event.kind() == StandardWatchEventKinds.ENTRY_DELETE) {
    System.out.println("Delete: " + event.context().toString());
    }
    if (event.kind() == StandardWatchEventKinds.ENTRY_MODIFY) {
    System.out.println("Modify: " + event.context().toString());
    }
    }

    } catch (Exception e) {
    System.out.println("Error: " + e.toString());
    }

    Move out of Member Introductions section.

    When you see a new file, can you come back a little later to see if its size has change? That still won't guarantee that there is more data to be written to a file.

    Please edit your post and wrap your code with
    [code=java]
    <YOUR CODE HERE>
    [/code]
    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.
