Share a folder in Windows 10/8/7 | Share Network File Access in 4 Steps
Microsoft Windows allows folders to be shared across a network, allowing desktops and laptops to access the files in these folders without having physical access to the computer where the folders are stored. When a folder containing documents or videos is shared, anyone with access can open, edit, save, and delete the files and folders if permissions allow it.
The easiest way to find a list of shared network folders is to use File Explorer (Windows 10) or Windows Explorer (Windows 8 and Windows 7).
Open Windows Explorer, go to the Folders pane and select Network.
