Fixing File Paths to Run on Multiple Computers

I have a Matlab program that needs to run on multiple computers, however the program searches for folders that are outside of the directory. I am stuggling to figure out how I can change file paths so that they work on multiple computers.

Here's my issue:

if ~exist('C:\Users\nperson\Desktop\F-DAS Matlab\ProcessFiles', 'dir') %check to see if processfiles folder exists
    mkdir('C:\Users\nperson\Desktop\F-DAS Matlab\','ProcessFiles') %create the folder if it doesn't
end
    cd('C:\Users\nperson\Desktop\F-DAS Matlab\ProcessFiles') %change current directory to processfiles 
    
copyfile('C:\Users\nperson\Desktop\F-DAS Matlab\RAW', 'C:\Users\nperson\Desktop\F-DAS Matlab\ProcessFiles') %copy files from RAW data to the processfiles folder

As you can see all file paths use 'C:\Users\nperson\Desktop\F-DAS Matlab\..' which will only work on my computer, how can I use relative file paths so it works on multiple computers.
