Windows to Windows with an Ethernet Cable

Connect the two computers with an ethernet cable. Plug one end of the ethernet cable into the square port on the back of your desktop PC, then plug the other end of the cable into the matching port on the side of your laptop.

Open the Control Panel on the first computer. You can do this by typing control panel into the search bar next to the Windows menu and clicking Control Panel in the search results.

Click Network and Internet. It should be on the left side of the Control Panel page. If your Control Panel page has "Small icons" or "Large icons" in the top-right corner, skip this step.

Click Network and Sharing Center. This opens a list of all current connections, including your Ethernet connection to the laptop computer.

Click Ethernet. It's a link to the right of the "Unidentified Network" connection in the right panel.

Windows to Windows Wirelessly

Connect the Windows desktop and laptop computers to the same Wi-Fi network. As long as both PCs are connected to the same Wi-Fi network, accessing the other computer to share files will be simple. You can also use this method if both computers are connected to the same network using an ethernet cable, such as through a router or switch. The steps are similar in both Windows 10 or Windows 11.

Open File Explorer on the computer that has files you want to share. You can do this on both the desktop and the laptop computer if you want folders to be accessible from both sides. File Explorer is the folder icon on the taskbar or in the Windows menu.

Right-click the folder you want to share and select Properties. A dialog window will expand. You can also share individual files instead of folders if you'd like.

Click the Sharing tab. It's at the top of the window.

Click the Share… button. This opens a window that lets you share the folder with certain people.

Select the user you want to share with. Click the menu to see a list of accounts, and then choose the account you want to share with. Click Add to add that user. By default, the file or folder is automatically shared with the owner's account. If you sign in to both the laptop and the desktop using the same account, you don't have to add any other accounts.

Choose permissions for the shared content. If you're sharing with another account, Read permissions are assigned by default. If you want to give that account full permissions, click the drop-down menu next to "Read" and choose Read/Write. If you're the owner of the file and plan to sign in with the same account on both computers, you don't need to adjust permissions—you already have full permissions.

Click the Share button. This shares the file with the selected user(s). If network discovery and file sharing are not turned on, you'll be prompted to turn these services on now. You can choose No if you're currently on a private network, such as at home, or Yes if you want to enable file sharing over public networks (such as coffee shops and college campuses).

Open File Explorer on the other computer. Now that the folder or file is shared on one computer, you can access it from the other.

Click Network in the left panel. This displays computers on the network that have shared files. If this computer doesn't have network discovery and file sharing turned on, you'll need to turn it on now. Click the yellow bar at the top of the window, and then choose No if you're currently on a private network, or Yes if you want to enable file sharing over public networks.

Double-click the name of the computer that's sharing the files. You'll be prompted to sign in.

Log in with the account that has permission to access the shared files. Once you're signed in, you can access the shared files in the selected folder.

Mac to Mac Wirelessly

Connect the laptop and desktop to the same Wi-Fi or LAN network. If your MacBook and Mac desktop are both connected to the same network—either wirelessly or wired through a router or switch—it's easy to set up file sharing between the two.

Open System Preferences on the Mac with files to share. For example, if you want to be able to access a folder that's located on your desktop while you're using your MacBook, open System Preferences on your Mac desktop.

Click the Sharing icon. It's the blue folder with a plus sign.

Check the box next to "File Sharing." You'll see this option in the list of services in the left panel. This turns on file sharing.

Add the folder(s) you want to share. To do so, just click the + under "Shared folders" in the right panel, browse to the folder, select it, and then click Add. Repeat for all other folders you want to share.

Choose who can access the shared content. Select the folder you're sharing, and then choose an account in the "Users" section to share with. You can also click + to share with an account that isn't listed here. You can choose Everyone to make the files available to anyone who connects to your network, or select a group to make the file available to everyone in that group.

Choose which permissions to assign. Next to each user, you can select what type of permission they'll have—for example, if you want full access to the folder when you're logging in from your desktop or laptop, assign all permissions (Read & Write). The folder or file(s) are now shared.

Connect from the other Mac in Finder Mac Finder. Now that you're sharing a folder or files from one of your Macs, you can open Finder on the other Mac to access the shared files. Open Finder, and then: Click Network under "Locations" in the left panel. After a moment, you'll see the name of the other Mac in the list. Double-click the name of the other Mac. Click Connect As at the top-right corner. Log in to the other Mac using any active account. You can now drag and drop files between the desktop and laptop.

Mac to Mac with a Thunderbolt 3 or 4 Cable

Check for a Thunderbolt 3 or Thunderbolt 4 port on your Mac. Most modern Macs from 2016 and later have this type of port. Look for an oval port with a lightning bolt near it on the laptop and the back of the Mac desktop. Transferring files over Thunderbolt is a lot faster than transferring files over Wi-Fi. You can also visit https://support.apple.com/en-us/HT201736 to find out which Mac models have Thunderbolt 3 and 4 ports.

Connect the two Macs with a Thunderbolt 3 or Thunderbolt 4 cable. You'll want to make sure the cable you use is specifically labeled as "Thunderbolt 3" or "Thunderbolt 4," as there are other cable types with the same style of connector. If one of your Macs has Thunderbolt 2 instead of Thunderbolt 3 or 4, you can use a Thunderbolt 2 to Thunderbolt 3 adapter.

Open System Preferences on one of the two Macs. You'll want to complete these remaining steps on both the laptop and the desktop Mac. System Preferences is located in the Apple menu at the top-left corner of the screen.

Click the Network icon. It's the globe icon.

Select Thunderbolt Bridge. You'll see this option in the left panel. Once choosing this option on both Macs, the status on the left under "Thunderbolt Bridge" will change to "Self-assigned IP." Once you see this, you can start transferring files from one Mac to the other. If you don't see this option, click the + below the list of connections in the left panel, select Thunderbolt Bridge from the "Interface" menu, and then click Create.

Connect to the other Mac in Finder Mac Finder. Now that the Macs are connected with a Thunderbolt bridge, you can access files over the network. On either of the two computers, open Finder and do the following: Click Network under "Locations" in the left panel. After a moment, you'll see the name of the other Mac in the list. Double-click the name of the other Mac. Click Connect As at the top-right corner. Log in to the other Mac using any active account. You can now drag and drop files between the desktop and laptop.
