When files are transmitted between different local networks, it is very slow to open the computer of the other party, and the operations are complicated. We can use some tips to reduce these troubles.
For example, right-click the "my music" folder on computer B, select "share", set "My music" to full sharing, and set the access password. Computer A finds the "my music" folder of computer B in "Network Neighbor". After double-clicking the folder, the system prompts that the password is required. Enter the password, select the "Save this password to the password table" option, and click the "OK" button. The password will not be prompted every time you send a file to this folder.
Then open another window on computer A and display the window and the "my music" folder icon on computer B on the desktop, right-click the "my music" icon on computer B, move it to the "send to" sub-folder, right-click it, and select the "Create a shortcut in the current position" option, in this way, you can create a shortcut for this directory.
Now, you only need to select A file on computer A and right-click it. You can run the "send" command to copy the selected file to the "my music" folder on computer B.
