No such file or directory for a found file.

files = dir("Aero Lab Airfoil Testing/2002 Aero Lab 2 - Group Data/*.csv");
for n=1:length(files)
load(files(n).name, "-ascii");
end
I have this code to load in and read several .csv files at once. When I run it, I get the error
>> airfoil
Error using load
Unable to read file 'AirfoilPressure_S301_1.csv'. No such file or directory.
Error in airfoil (line 3)
load(files(n).name, "-ascii");
I'm not sure how there could be an issue with the file not existing when the code is locating the file in the directory. Any help would be appreciated.

Try this:
topLevelFolder = fullfile(pwd, 'Aero Lab Airfoil Testing/2002 Aero Lab 2 - Group Data');
filePattern = fullfile(topLevelFolder, '**\*.csv');
fileList = dir(filePattern);
for k = 1 : numel(fileList)
thisFullFileName = fullfile(fileList(k).folder, fileList(k).name);
fprintf('Reading %s...\n', thisFullFileName);
data = readmatrix(thisFullFileName); % or csvread()
end

files(n).name is just the file name, not the full path to the file, so you have to cd to the directory and/or refer to the file by its full path
