#-Link-Snipped-#, Can you post your code snippet where you read the main file and write the data to user specific file?

With this approach you dont even have to generate the files specific to every user if that's not your ultimate goal. If your ultimate goal is to just group the...

How about this approach, First, parse the entire file and during parsing, maintain a map of key value pairs with key as userid and value as a linked list of...
