Saves file as read only

Hey, I am currently using Rhino 7, pretty new to using rhino. But whenever i go to save things, either as save, or ‘save as’, it automatically comes up with you do not have access to this ‘Hardrive,’ and saves as read-only. I was wondering if there is any way for me to save these rhino files to my harddrive, and still be able to have an editable file, not just read only.

Thanks, kelly.
