Having trouble importing data from file with same name in different folders

I am trying to import data from multiple participants in MatLab. I think I am having trouble because the file names that are being imported are all the same but are under different directories. I have used fullfile to find all these file names and place them into the structure but when I am trying to import the data, I end up having repeats in each of the columns. I think this is due to the file names being similar. Here is some sample code.

totalFiles=dir(fullfile(mydir, 'pt*','scan*', 'data.txt')); 
numTotalFiles=length(totalFiles); 

for i=1:numTotalFiles
    filename = [totalFiles(i).name] ; % all of the totalFiles(i).name = data.txt (but placed in different directories)
    num2 = importdata(filename, ' ', 131); % hidata starts at line 131
    hidata = num2.data;
    alldata (:,i) = hidata (:,1); % all of columns end up being the same as totalfiles(1).name rather than totalfiles(i).name
end

Use fullfile with the folder field of totalFiles to construct the full-path name of each file:

totalFiles=dir(fullfile(mydir, 'pt*','scan*', 'data.txt')); 
numTotalFiles=length(totalFiles); 

for i=1:numTotalFiles
    
%     filename = [totalFiles(i).name] ; % all of the totalFiles(i).name = data.txt (but placed in different directories)
    filename = fullfile(totalFiles(i).folder,totalFiles(i).name);
    
    num2 = importdata(filename, ' ', 131); % hidata starts at line 131
    hidata = num2.data;
    alldata (:,i) = hidata (:,1); % all of columns end up being the same as totalfiles(1).name rather than totalfiles(i).name
end
