- what is GetTagNumber()?

- why the detour, why not just have a global imageIndex that increments by 2?

- the MSDN example sets TreeView.ImageList after the list has been loaded.

And of course you should use a try-catch: there is input/output involved, it can always
fail (some one/some process could move/delete a file/folder before you could click OK,
a network drive could suddenly get disconnected, etc.)

try
                {
                    //Passed a FileStream to c'tor of StreamWriter, with sharing mode
                    _fileController = new FileStream(_fileName, FileMode.Create, FileAccess.Write, FileShare.Read);
                    _fid = new StreamWriter(_fileController);
                }

//fsArr is an array of FileStreams.
fsArr[index] = new FileStream(fileName, FileMode.Open, FileAccess.Read);

First of all, the code you use to create a FileStream object creates new file so the second instance of your application will try to create file which was created by first instance and not open for reading.
