AIR- detect directory change Windows desktop - windows

Question

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?

Answer 1

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;
}
