I have a router 4 machines, how to build a local area network, so that hard disk things can be share

Put those files in a shared document.

3. Then, in the pop-up control panel page, click the [Change Advanced Sharing Settings] option, as shown in the figure below, and then proceed to the next step.

4. Then, in the pop-up window, check it according to the icon, as shown in the figure below, and then enter the next step.

5. Then, find the file or folder you want to share, right-click and select "Properties", select the [Share] tab, click the [Advanced Sharing] button, and then select the [Share this folder] option, as shown in the figure below, and then enter the next step.

6. Finally, after repeating the above steps for the other two computers, you can view the other two computers in the "Network" menu of any of the three computers, and you can share the files, as shown in the figure below. In this way, the problem is solved.

<>2. After entering [View Network Status and Tasks], in the new window that pops up, find and click [Change Advanced Sharing Settings] in the left menu, as shown in the figure below;

3. After entering [Change Advanced Sharing Settings], you can configure it according to the current network status, and all these options must be enabled, as shown in the figure below;

4. Finally, when you open the shared folder, you can see the shared files placed in the shared folder, which can be viewed and modified.

The two computers pass through the LAN interface of a router, which is in a local area network, and there is no need for any work-sharing tools, just share the hard disk you want to use and release the read and write permissions.

1.Do you mean two computers share a hard drive? In this case, you can connect this hard drive to one of the computers, share the computer on this computer, and set up disk mapping on the other computer. On My Computer - Tools - Map Disk Drives.

2.If you want to use one hard drive for two computers, not every computer has a hard drive.

You see if you have a LAN sharing tool on your computer, and if you do, just run it.

It's simple.
