Problem moving files

I have recently installed two airports which the installation program put into the community folder. But I cannot move these to my Addons folder - I am refused permission (even in DOS command mode). So my community folder now has dozens of links to Addons and two airport folders that cannot be moved. I’d like to have all my addons in the Addons folder for ease of use in MSFSAddons (and to be tidy!). Anyone encountered and solved this issue?
