I am using this code in order to merge vertically .txt files. Command error shows me that:
Error using fscanf
Invalid file identifier. Use fopen to generate a valid file identifier.
Error in test_V2 (line 51)
data = fscanf(fid_t,'%c');%read data
My code is:
fid_p = fopen('FINale.txt','w'); % writing file id
x= dir ('Fin*.txt');
for i =1:length(x)
filename = ['Fin',num2str(i),'.txt'];%filename
fid_t=fopen(filename,'r');%open it and pass id to fscanf (reading file id)
data = fscanf(fid_t,'%c');%read data
fprintf(fid_p,'%c',data);%print data in File_all
fclose(fid_t);% close reading file id
fprintf(fid_p,'\n');%add newline
end
fclose(fid_p); %close writing file id
Could you help me please?

You are probably creating the filename incorrectly in the line
filename = ['Fin',num2str(i),'.txt'];%filename
Try the following code
fid_p = fopen('FINale.txt','w'); % writing file id
x = dir('Fin*.txt');
for i =1:length(x)
filename = fullfile(x(i).folder, x(i).name);%filename
data = fileread(filename);%read data
fprintf(fid_p,'%s\n', data);%print data in File_all
end
fclose(fid_p); %close writing file id

Thank you. I have tried your code and it works. But there is a problem. Between each line there is an empty line without data. I would like to "remove" this line. How could I make it?

Try writing without the newline character at the end. For example, change the fprintf() call to
fprintf(fid_p,'%s', data);%print data in File_all
