How to know when a file or folder is accessed (in real time)

I need to show some data when users access folders and files in SharePoint 2010. Each item has its own data, so I need to raise an event when开发者_StackOverflow社区 they access a certain file/folder and then show the propoer data in a webpart.

Is it possible to do that?

Thanks in advance!

You need to enable Item level Auditing and then read the Audit log:

i think you need to create event handler to raised the event on itemupdating.

hope this help.
