I am having problems using commands like copy and paste in Windows 11 File Explorer when trying to copy large files between my PC and my NAS.
I can navigate around and see all the files on my NAS from within file explorer and I can also open up files.
However, when I try to copy and paste files in either direction between my PC and my NAS file explorer hangs and won't perform the task. Also if I right click on a file the menu takes over a minute to appear.
After trying various possible ways to fix the problem I have found that by turning off the Bitdefender Firewall the problem goes away and everything works normally.
Can someone tell me how to properly set up an exception that will prevent the firewall interfering so I don't need to keep turning off the firewall.
