AIR- detect directory change Windows desktop

Discovered a class for detecting directory changes but only seems to work on Mac Desktop, NOT Windows.

https://github.com/renz45/Actionscript/tree/master/Air/filesystem

The FileMonitor class only detects changes for single files I believe.

Does anyone know of a way to detect directory changes with AIR on Windows desktop?

Solution

The monitor checks for the modification time of folders only. On Windows the folder modification time update behaviour is very unreliable, try to add a new file, you'll probably see that it updates the folders modification time, while it doesn't when changing the contents of a file.

For a more reliable behaviour you would have to check the modification time of all files and subfolders.

Here's an example, a changed DirectoryMonitor.traverseDirectoryTree method which also includes the files. It's not thoroughly tested, and with a growing number of nested files and folders you might run into performance problems, but in the end it's just an example.

private function traverseDirectoryTree(dir:File):Vector.<File>
{
    var list:Vector.<File> = new Vector.<File>;
    list.push(dir);
    for each (var file:File in dir.getDirectoryListing())
    {
        if(!file.isHidden)
        {
            list.push(file);
            if(file.isDirectory)
            {
                list = list.concat(traverseDirectoryTree(file));
            }
        }
    }

    return list;
}
