Reagrding reading file name

I have some text data file which is from 1970:5:2000 the file name is v_CH_1970_II_1A.txt,

v_CH_1975_II_1A.txt,

v_CH_1980_II_1A.txt.....till 2000.

in the same folder I have some other data which has file name v_CH_1970_II_1A.txt

v_CH_1970_II_1A2.txt

v_CH_1970_II_1A3b.txt

v_CH_1970_II_1A6a.txt ---- ( different 13 files)

v_CH_1975_II_1A.txt

v_CH_1975_II_1A2.txt

v_CH_1975_II_1A3b.txt

v_CH_1975_II_1A6a.txt ---- ( diffrent 13 files)

So I would like to read all major years from 1970:5:2000 same time I want to read data from other 13 different files for individual year e.g for 1970

v_CH_1970_II_1A.txt

v_CH_1970_II_1A2.txt

v_CH_1970_II_1A3b.txt

v_CH_1970_II_1A6a.txt

---- ( diffrent 13 files)

somebody please tell me how I can set for loop so I can read both data sets same time?

for k=1970:5:2000
  FileStr=sprintf('v_CH_%d_II_1A*.txt');
  Files=dir(FileStr);
  for j=1:length(Files)
      data=textread(Files(j).name);
  end
end

there are some files in different files

v_CH_1970_II_1A_Exe.txt

v_CH_1970_II_6b.txt

v_CH_1970_II_1b.txt

v_CH_1970_II_7.txt

So the structure of name is not constant , so how I can read in this condition

Change this line

FileStr=sprintf('v_CH_%d_II_*.txt');
