unzip file.zip
ls *.file
file.file
str = fileread('file.file')
str =

The code in my answer uses fileread, so I guess you are trying to run the code in my comment, which is for combining multiple files into one. Since you don't have readlines, try this instead:
unzip file.zip
ls *.file
file1.file file2.file
directory = '.'; % directory where your files are
output_file = 'all_files.file'; % output file to write, containing contents of all files
files = dir(fullfile(directory,'*.file'));
files = fullfile({files.folder},{files.name});
N = numel(files);
C = cell(N,1);
for ii = 1:N
C{ii} = regexprep(fileread(files{ii}),'\r?\n$','');
end
fid = fopen(output_file,'w');
fprintf(fid,'%s\n',strjoin(C,newline()));
fclose(fid);
% check the result for these two files
type(output_file)

C = regexp(str,'([^\r\n]+)\d{2}{''y'':(.+?), ''x'':(.+?), ''z'':(.+?)} {''a'':(.+?), ''b'':(.+?), ''c'':(.+?)}','tokens');
