This works fine monitoring a folder/directory (dispatches a change event if a file within the folder is either created, removed, or modified)… But it does not seem to recurse into any sub-directories. Is there an easy way to get it to do this? If not I suppose the best thing would be to manually recurse into the directory and add a new monitor for every subdirectory… but that may get resource intensive seeing as this is running off timers.

Good day, Mike Chambers!
First of all, thank you for intersting and usefull article about files monitoring.

I create sample project, download last .zip archive of as3core library (there is no air.filesystem package, but a manually add neccessary files FileMonitor.as, FileMonitorEvent.as, FileUtil.as, VolumeMonitor.as).

But, when I run the project – I got exception at
FileMonitor.as line 135:
if(timer.running)… // here timer object is null

So, could you send me sample project?

Thx

hi–Is there a way to do this without using a Timer do constantly poll for changes? I’d like to see something truly event driven–something that is triggered by a system event, rather than polling every ms to see if there’s been a change–a true listener.

Anyway to monitor a folder which returns the file name that is being changed? I have used f.browseForDirectory(“select a folder”);
which works perfectly. However, it does not return the file name of the file that is being changed.

damn, never mind. I thought the FileMonitor would allow to monitor a folder, and would let you add events to see what files changed, where they have moved e.t.c

Cheers Mike,
awesome work! I wanted to make an air app that would allow syncing of your directories on an ftp server using the ftp protocol.

How intensive is FileMonitor performance wise. I’ve seen some air apps which hog alot of RAM, would monitoring 1000 Files kill your machine?

Now that I have this code I can take over the world and also avoid writing a text editor. Thanks!

hi,

i think there’s a bug in the watch()/unwatch() methods: if you call unwatch() and then watch() again, the timer is not restarted because the listener was removed in the unwatch() method. this could be fixed by setting timer=null at the end of the unwatch() method. further, it’s not clear that watch() has to be called again when a new file is set with the file-setter (because it calls unwatch() internally). otherwise it’s a helpful class, thanks!
