Hi,
I have a multiple files I need to read in 39 sub-folders in Home directory. For example:
Home\folder1\Output_1 Home\folder2\Output_2 .. Home\folder39\Output_39
What is the MATLAB function I can use to open all the sub-folders so that I can use importfile function to read all Output files from 1 to 39.
Thanks in advance for the help.

for k=1:39
f=sprintf('Home\\folder%d\\output_%d',k,k)
% read f
end

I did the following but it returns nothing and gives an error message. (See below). Sub_folder name are Pts001, Pts002,...upto Pts0039 so I modified your code. In each sub-folder file names are Output_1, Output_2....upto Output_39. There is no value in f.
addpath('C:<path>\Generated_39');
for k=1:39 f=sprintf('Pts%d\output_%d',k,k); end
Warning: Escape sequence 'o' is not valid. See 'help sprintf' for valid escape sequences.
Thanks,

Notice how you use a single backslash and Azzi used a double backslash? It makes a difference. But why not just use a single forward slash instead? It works just fine in Windows - Windows does not require backslashes.
