I want to know is this the right way to find whether the existing file is modified or not ?

IMHO there is no 'right way' or 'wrong way'. It all depends on the goal you wish to achive. If this works for you, go ahead.

One thing you should be aware of, is the race condition you are introducing: what is someone edits the file after you read it, and before you stumble over it? You should introduce some kind of locking mechanism to be sure you get it right!

Cheers,
