hello everyone, i wrote this code to read text files with extension YO7, each file represents a month in the year, when i run it for 2 cards (2 months) it works, but when i add the third card or month it gives error, any ideas what to do here please?

for K = 1 : length(directory)
    filename = directory(K).name;
    fileID = fopen(filename,'r');
    formatSpec = '%s';
    A_cell = textscan(fileID,formatSpec);
    A=char(A_cell{1,1}{:,:});
    A(find(isnan(A)))=0;
      [rows,columns]=size(A);
      if columns~=105
          ArrayTemp=zeros(rows,105);
          ArrayTemp(1:rows,1:columns)=A;
          A=ArrayTemp;
          A=char(A);
          A(isspace(A)) = '0';
      end
      x1=filename;
      xtr=strcat('C:\Users\maa285\Desktop\New folder (2)',x1);
      fid = fopen( xtr, 'wt' );
      StationID = A(:,4:9);
      Year_of_Data = A(:,12:13);
      Month_of_Data = A(:,14:15);
      Vehicle_Class = A(:,20:21);
      Total_Weight_of_vehicle = A(:,25:28);
      Number_of_axles = A(:,29:30);
      A_Axle_Weight = A(:,31:33);
      A_B_Axle_spacing = A(:,34:36);
      B_Axle_Weight = A(:,37:39);
      B_C_Axle_spacing = A(:,40:42);
      C_Axle_Weight = A(:,43:45);
      C_D_Axle_spacing = A(:,46:48);
      D_Axle_Weight = A(:,49:51);
      D_E_Axle_spacing = A(:,52:54);
      E_Axle_Weight = A(:,55:57);
      %This is to convert the string to numbers so it can show the output:
      fprintf(fid, '%s %s %s %s %s',StationID, Year_of_Data, Month_of_Data, Vehicle_Class, Total_Weight_of_vehicle, Number_of_axles, A_Axle_Weight, A_B_Axle_spacing, B_Axle_Weight, B_C_Axle_spacing, C_Axle_Weight, C_D_Axle_spacing, D_Axle_Weight, D_E_Axle_spacing, E_Axle_Weight);
      Ans_3{K}=str2num(StationID);
      Ans_6{K}=str2num(Year_of_Data);
      Ans_7{K}=str2num(Month_of_Data);
      Ans_10{K}=str2num(Vehicle_Class);
      Ans_12{K}=str2num(Total_Weight_of_vehicle);
      Ans_13{K}=str2num(Number_of_axles);
      Ans_14{K}=str2num(A_Axle_Weight);
      Ans_15{K}=str2num(A_B_Axle_spacing);
      Ans_16{K}=str2num(B_Axle_Weight);
      Ans_17{K}=str2num(B_C_Axle_spacing);
      Ans_18{K}=str2num(C_Axle_Weight);
      Ans_19{K}=str2num(C_D_Axle_spacing);
      Ans_20{K}=str2num(D_Axle_Weight);
      Ans_21{K}=str2num(D_E_Axle_spacing);
      Ans_22{K}=str2num(E_Axle_Weight);
      %%to return the separated vectors into one new matrix with usable data:
        all{K} =[Ans_3{K},Ans_6{K},Ans_7{K},Ans_10{K},Ans_12{K},Ans_13{K},Ans_14{K},Ans_15{K},Ans_16{K},Ans_17{K},Ans_18{K},Ans_19{K},Ans_20{K},Ans_21{K},Ans_22{K}];
