Open a file error, even though path is valid and correct

I am new to Matlab and had help writing my code, but even though the path is correct I cant get my file to open.

close all, clear all  clc
% note I've renamed the files, call them what you like but they need to
% have the year in them to load in a loop

dir=('"C:\Users\Madison-Riley\Desktop\Copernicus Data"');
%look at one file to interrogate and understand dimensions and variables
ncdisp([dir,'June1972.nc'])

Error using internal.matlab.imagesci.nc/openToRead
Could not open "C:\Users\Madison-Riley\Desktop\Copernicus Data"June1972.nc for reading.

Error in internal.matlab.imagesci.nc (line 124)
this.openToRead();

Error in ncdisp (line 71)
ncObj = internal.matlab.imagesci.nc(ncFile);

% test=ncread([filepath,'June2021.nc'],'uo'); whos test

% check all your files, June2019 only had one timestep so I couldn't work with that??
% same for June2020
time=ncread([filepath,'June2022.nc'],'time'); whos time
ntime=length(time);

% get coordinate data, assuming it's the same between all files
lon=ncread([filepath,'June2021.nc'],'longitude');
lat=ncread([filepath,'June2021.nc'],'latitude');
[LON,LAT]=meshgrid(lon,lat);

I don't understnad the issue. My file is coming from the exact directory and that is teh fil;e name. I am trying to create a mean across 50 years for June (1972-2022). June 1972 was sued to understand my dimensins and variables. June 2021 was used to recieve coordinate data.

Do not use the "" in the directory name.

dir = 'C:\Users\Madison-Riley\Desktop\Copernicus Data';

Do not put filenames together using [], use fullfile() instead

time = ncread(fullfile(filepath,'June2022.nc'),'time'); whos time

I removed the "" and it still will not load the file.

I adjusted hte filenames, they are all called filepath not dir, but the second line of code will not open.

[Stephen23]

fp = 'C:\Users\Madison-Riley\Desktop\Copernicus Data';
ncdisp(fullfile(fp,'June1972.nc'))

Unforunatly, I still recieve the same error,just with fullfile.

close all, clear all  clc
% note I've renamed the files, call them what you like but they need to
% have the year in them to load in a loop

fp = 'C:\Users\Madison-Riley\Desktop\Copernicus Data';
ncdisp(fullfile(fp,'June1972.nc'))
