how to use sprintf with fullfile

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?

i try to use only

Filename = fullfile(myFolder,baseFilename);

but it can't read the file.I need to use sprintf actually..to read all the values as a string (in each file).

[Walter Roberson]

baseFilename already includes the .txt part . Just

Filename = fullfile(myFolder,baseFilename);

should work

thank you very much to both of you..
