How to get notified when a folder is accessed?

I have a shared folder on my local machine. I want to get notified every time someone tries to access it. Could someone give me some hint on this?

I have checked the FileSystemWatcher class, it only provides events for change/creation/delete/rename of the contents under the folder, which is not exactly what I want.

I also tried to use the event log audition as shown here, but it is just not exactly what I want, either.

Many thanks.

as far as i know the filesystemwatcher fires a changed event if the files are only accessed and if the files are modified.

Might also be something not exactly what you want but you can list connections using wmi, check http://stackoverflow.com/questions/1448384/monitor-windows-share

To get this information you need a File System Filter Driver.

So i just found the commercial vendor that offers a driver with a .Net API: Eldos Callback Filter

Thanks Oliver. I thought about the File System Filter Driver. But kind of itimidated by the complexity. Since you mentioned it, too. I will take a look. Thanks. :)

a while ago i stumbled across a commercial product where they implemented such a driver and gave you a .Net API on the other side. But i just can't find it anymore. :-((

@Oliver - if you ever remember, please post here :)

@Cocowalla: A search today leads me to the wished result. Take a look into my updated answer.

Thanks Oliver - this looks really good, though the pricing looks like it's on the high side. I'll check out the trial version

Cocowalla 2010-07-27 07:26:43

@Cocowalla: Yes the prices are really high, but if you see the complex problem they solved and how many programming hours needed i think the price is okay (if it works as expected, never tried it on myself!)

I just tried this out and within a few minutes it rebooted my machine, without warning. I think they have some reliability issues, so with regret I don't think I can use this :(

Cocowalla 2010-07-27 13:16:24

I let the sales guy who contacted me with the trial license know about my problem... wow, I've never known a sales guy to be so damn rude! Not getting a good impression at all, which is unfortuanate because I can't find anything similar :(
