Just a quick note, FileSystemWatcher in .NET is actually not recommended for use by Microsoft.
It does not guarantee that an event will be raised on every new file or file mod in a given folder… and it's even less determinstic when trying to deal with network share drives. Microsoft's own developer blogs usually recommend that people roll their own polling-based solution instead of depending on FileSystemWatcher (googling FileSystemWatcher will yield many many results regarding this). I'm not necessarily saying that the overall idea is without merit… but it's just that if someone does want to try and implement something like this on Windows, they should try and avoid whatever Win32 API calls that FileSystemWatcher uses. --Mike On Feb 14, 2013, at 6:03 AM, Ivan Enderlin @ Hoa <ivan.ender...@hoa-project.net> wrote: > Hi internal, > > A missing feature in PHP is a file system watcher/monitoring available for > almost all platforms.
