I have Libra Office on a laptop and a PC, can I link these two

I have documents and photos on my laptop and differrent documents on my stand alone PC.

If you have a network (WiFi or Ethernet cable based), you can

  • Share PC folder(s) → Laptop
  • Share Laptop folder(s) → PC

as long as both computers are powered on.

But this question got nothing to do with LibreOffice.

You could also use a cloud based service that has a local folder for synchronizing such as Dropbox.

You save a file to the folder and it will be synchronised to the server when computer A is connected to internet. If computer B then connects to internet its local folder will synchronise to the server, picking up the new file written by computer A
