It's easy to lose track of which files and folders you've set to be shared in Windows with other users since you don't always want them to be shared with everyone.
Shared Folders List in Windows
Good thing there's a list of all the shared files hidden on your system - to get there, search for Computer Management in the Start menu.
On the left pane of the CM window, browse for Computer Management (Local) > System Tools > Shared Folders > Shared:
You'll get a list of items here that are shared by your computer with the path and description given.
