How to quickly find added / removed files?

Question

I am writing a little program that creates an index of all files on my directories. It basically iterates over each file on the disk and stores it into a searchable database

Answer 1

Unfortunately there's no standard way to listen to file system events in java. This may be coming in java7.

For now, you'll have to google "java filesystem events" and pick the custom implementation that matches your platform.
