Original Problem We have two directories plaintext and secret, which hold the unencrypted files and their encrypted counter parts respectively. We need to detect changes to plaintext and sync them to secret. Common Methods Polling Based The simplest method is to check the directory on a regular interval (polling) for changes by walking the directory and its files and comparing it against the cached last known state. This method can be less efficient and timely than the other two methods below but it’s biggest advantage is it is the least OS dependent....
