How to remove the lock symbol on a file - no homegroup present

Hello forum,

I have been trying to figure out how to change the status of a file that is present on network discovery on another computer.

I am just going through and assessing each file.

I notice the only person I really would like to share with is anyone that uses the external hard drive - much like the other files on the hard drive that do not have a lock on it.

I know that it may be basic - but I just want a work around for the few folders that I managed to see in computer management.

If someone could please give me a basic idea of what menu's to go into - I promise I will not change the behaviour of any folders.

Thank you.

Just basic steps -

As I am on a network/workgroup and do not want the homegroup - what is the best option.
