I was trying to back up my RTX world to a flash drive and I'm only met with "your organization does not allow you to place this file here." 

Mind you this world was made previous to RTX and I backed it up BEFORE I joined the Beta so it is a beta exclusive problem. This problem also persists for worlds created in the beta that do not have any RTX enabled resource packs. 

Should also note that I am the single user on this PC and all the files have the correct ownership settings, and permissions needed. Windows is up to date and I have no other issues with any other files outside of the beta.
