Need to transfer a huge video file or share documents with another computer in your house or office? Forget about finding a USB flash drive. Windows allows you to easily share folders over your Wi-Fi or Ethernet network.

Here is how to securely open access to any folder on your PC:

1. Right-click the folder you want to share and select Properties.

2. Go to the Sharing tab at the top and click the Share... button.

3. In the drop-down menu, choose who to share it with. Select Everyone if you are on a trusted home network, and click Add.

4. Under the "Permission Level", choose Read (they can only view files) or Read/Write (they can edit and delete files). Then click the Share button at the bottom.

5. Next, click on the Advanced Sharing... button in the same Properties window. Check the box that says Share this folder and click OK.

Now, go to the other computer, open File Explorer, and click on Network in the left sidebar. You will see your first PC listed there, and inside, your shared folder will be waiting!
