how to read file

I have a data in the form of a picture below, in each of the six files with the extension .csv, I get the error as below. What Matlab code do you suggest?

Unable to find file or directory 'human1_antalgic1_SkeletonData1'.

c = 'C:\Users\HAMSHARI\Documents\MATLAB\movementdisorder';
files = dir(fullfile(c,'*','*Skeleton*.csv'));
n = numel(files);
DATA = cell(n,1);
for k=1:n
    str = fullfile(files(k).folder, files(k).name);
    DATA{k} = readmatrix(str);    
end
for i= 1:10
    for j = 1:20
            str = sprintf('human%d_normal%d_SkeletonData%d', [i j]);
            data = readmatrix(str);
        end
end

seems to me (according to the pic) your path should end with \data whereas in your code it ends with \movementdisorder

therefore the error msg
