This article shows you how to share a folder on the network. In this way, all computers connected to the same LAN will be able to access its content, modify it or add new documents and files. It is possible to share a folder on both Windows and Mac systems. However, it should be noted that the computer hosting the shared folder and the one from which you want to access it must be connected to the same LAN. If you need a shared folder to always be synchronized with other devices (including a USB stick), you can use the FreeFileSync program.
