How does MSMQ manage messages?
Does it store the messages in flat file?

I'm trying to implement a messages management system.

Answer 1

MSMQ uses flat files located in %windir%\system32\msmq.

If you want to implement your own queueing, I suggest you take a look at Ayende's blog post on queueing

Answer 2

it stores them as files on the disk.

If you wanna manage them use the System.Messaging API
