[Walter Roberson]

ext = '.txt';  %extension of files
dinfo = dir("*" + ext);
filenames = {dinfo.name};
nfiles = length(filenames);
all_data = cell(nfiles,1);

for K = 1 : nfiles
   thisfile = filenames{K};
   thisdata = load(thisfile);
   all_data{K} = thisdata;
end

The data is now in the cell array all_data .

Or you could process the data as you read it.
