C# Application FileSystemWatcher to handle replaced files

[xMetalDetectorx]

I am using FileSystemWatch er to monitor a directory for files that are created and replaced. It is working fine for new files, but if I copy a file into the directory with the same name and choose to replace the existing file, it doesn't trigger any event.

Does anyone know how to get that specific event? (Replace a file)

Thanks.

I would expect that it triggers the 'Changed' event. I see that every time I add a line to a text log file. There is a change in the 'last access time' so the file has a change.

I would expect that totally replacing the file must register as a change.

I have tried making the NotifyFilter = LastWrite, and added an event handler for Changed, but that is still not picking up replaced files (The new files have new Date Modified values).

oFileWatcher.NotifyFilter = NotifyFilters.LastWrite;

oFileWatcher.Deleted += new System.IO.FileSystemEventHandler(Deleted);
oFileWatcher.Created += new System.IO.FileSystemEventHandler(Created);
oFileWatcher.Changed += new System.IO.FileSystemEventHandler(Changed);

Any other ideas?

I got it to work with the above code, but for every replaced file, it fires 3 Changed events.....

It's the Chaged event that gets fired in this scenario, have set EnableRaisingEv ents to true ?

This is as described in MSDN, I'd guess your getting one for each attribute that changes. Try changing the NotifyFilter to get just the one. I think you'll always get more than one for a replace though.
