FileSystemWatcher Events in IDE

Question

FileSystemWatcher provide us different kind of events from changed to deleted. I was wondering why I'm getting deleted event whenever I used visual studio 2005 to edit a file and changed event if I'm using notepad or notepad++ and other editor?

Answer 1

Standard operation for programs that want to avoid losing everything:

1. Rename original file
2. Create new file with original name
3. Write and close file
4. No problems: delete file from step 1

If something goes wrong, the renamed file is restored. Your other editor would corrupt the original if something goes wrong while writing.
