Use FileSystemWatcher on a single file in C#

When I try to set the watcher path to a single file like so:

watcher.Path = filePath1;

I get the error:

The directory name C:\Cromos 3.0\repository\diagnostics\dwm01_2011_06_13__09_03.LXD is invalid.

Can you only set the path to a folder directory?

Your error is setting the Path property with a full filename

watcher.Path = Path.GetDirectoryName(filePath1); 
watcher.Filter = Path.GetFileName(filePath1);

should work.

Not related to your proper question, but, of course, to enable the FileSystemWatcher's functionality, it is imperative to set the EnableRaisingEvents property to true.

Yes, but you can watch for specific files by setting the filter property to the filename.

e.g.

watcher.Filter = "dwm01_2011_06_13__09_03.LXD";
