How to read a sequence of files with same extension and store it

Hello Everyone, I have N number of text cards, lets say 200 cards with similar extension, the extension is (07), I wrote a code to open each card individually and store it in vectors with fixed width columns. Now to import or export multiple files, how can I create a control loop to process one file at a time Automatically? knowing that each card has the same number of columns but different rows, Example one has 2500 rows and other has 1700 . %to read each card I wrote:
fileID = fopen('C77901XX.07','r');
formatSpec = '%s';
A_cell = textscan(fileID,formatSpec);
for i=1:size(A_cell{1},1)
A(i,:)=char(A_cell{1,1}{i});
end
and the code to separate columns is :
y=A;
[rows,columns]=size(A);
% % This for loop is to read the data row by row and store in different
% % matrices
for i=1:rows
Record_Type(i,:)=y(i,1:1);
FIPS_State_Code(i,:)=y(i,2:3);
Station_ID(i,:)=y(i,4:9);
Direction_of_Travel_Code(i,:)=y(i,10:10);
Lane_of_Travel(i,:)=y(i,11:11);
Year_of_Data(i,:)=y(i,12:13);
Month_of_Data(i,:)=y(i,14:15);
Day_of_Data(i,:)=y(i,16:17);
Hour_of_Data(i,:)=y(i,18:19);
Total_Volume(i,:)=y(i,20:24);
Class_1_Count (i,:)=y(i,25:29);
Class_2_Count (i,:)=y(i,30:34);
Class_3_Count (i,:)=y(i,35:39);
Class_4_Count (i,:)=y(i,40:44);
Class_5_Count (i,:)=y(i,45:49);
Class_6_Count (i,:)=y(i,50:54);
Class_7_Count (i,:)=y(i,55:59);
Class_8_Count (i,:)=y(i,60:64);
Class_9_Count (i,:)=y(i,65:69);
Class_10_Count (i,:)=y(i,70:74);
Class_11_Count (i,:)=y(i,75:79);
Class_12_Count (i,:)=y(i,80:84);
Class_13_Count (i,:)=y(i,85:89);
Class_14_Count (i,:)=y(i,90:94);
Class_15_Count (i,:)=y(i,95:99);
end
how can I please do this to the whole cards by one click? and by the way I wrote this to find the cards with the same extension in the folder:
path =pwd;
extension = '.07'
rtnFiles=dir(fullfile(path,['*' extension]))
Thank you guys

To read all the .07 files:
myfiles = dir('*.07') ;
N = length(myfiles) ; % total number of files
data = cell(N,1) ; % to store the data of each file into cell
% loop for each file
for i = 1:N
thisfile = files(i).name ;
% read the file/ do waht you want / you may run your code here
% data{i} = file data ; % store file data like this into cell
end

Copy your code here.....files should be a structure of all files with extension.07 present in the folder.
