If you want to check what files are shared then go to start->
run -> type cmd ->and then type this 'net share' without the quotes and you can see all the shared files and folders on your PC and you can disable sharing on them.

If you want to disable the file and printer sharing completely then you go to start -> control panel and -> click network setup wizard and click next and follow the prompts and on the final screen it gives you two options and select the 'Turn off printer and file sharing on your pc' and no one will be able to share you files anymore.
