I have the following code:
myFolder = 'D:\data';
myFiles = fullfile(myFolder,'*.txt');
allFiles = dir(myFiles);
for i = 1 : length(allFiles)
baseFilename = allFiles(i).name;
Filename = fullfile(myFolder,baseFilename,sprintf('%d%02d.txt',i));
fid = fopen(Filename);
A{i} = fscanf(fid, '%d %d %d');
fclose(fid);
end
I got an error 'invalid file identifier'. My Filename is incorrect. How should i write sprintf together with fullfile. My file names written as 0101,0102,...,6001,6002.txt.

Might be because
sprintf('%d%02d.txt',i)
You specified two formats but only one input. Maybe one of them is not needed?

baseFilename already includes the .txt part . Just
Filename = fullfile(myFolder,baseFilename);
should work
