Trowa,

You have to set the notify filter to know when the file copy is completed.

//set the notify filter
myWatcher.NotifyFilter = NotifyFilters.LastAccess | NotifyFilters.LastWrite
;

When the notify filter is set, the event wont be fired multiple times. You
will be notify when the entire operation is completed.

Hi,

I'm trying to use FileSystemWatcher to determine when a new file has been
added to a directory. However, after the file has been added, I need to
process the file. This results in a problem if the file is large and takes time to copy, as the events appear to get received before the copy is
finished.
I've tried listening to the Created event, as well as the Changed event
(which gets fired multiple times) based on the last write time. When
listening to the event, I try checking if I can open the file for exclusive access to determine if the copy operation is completed, but this still
doesn't seem to work all the time.
Any ideas would be greatly appreciated.
Thanks,

Michael

Trowa, Shakir,

When I use NotifyFilter, the change event still is fired several times
during a copy process. Is there any other way to determine with
FileSystemWatcher if such a file operation is finished ?

Try this.

myWatcher.NotifyFilter = NotifyFilters.LastAccess | NotifyFilters.LastWrite
| NotifyFilters.FileName | NotifyFilters.DirectoryName;

it should work now

I don't think so!!
The changed event will just fire more than once.
Search from this archive or google, you will find a lot
saying change event will fire more than once.
I just post a question a couple days ago..
Have you really tried that?
Try it, you will see the outcome..
All you can do is use flag and check in a timer_event or comparing trigger
time with
last_time_trigger..
Try this.

myWatcher.NotifyFilter = NotifyFilters.LastAccess | NotifyFilters.LastWrite
| NotifyFilters.FileName | NotifyFilters.DirectoryName;

it should work now
