Acces directories of specific name

Hi all,

I have a question on how to access specific sub-folders by name.

Lets say I have a working folder where there are sub-folders called:

-power

-thickness

I am using a GUI in which I use the following code to access the individual sub-folder of interest.

folder = uigetdir('C:\Users\...\working folder');
files = dir(fullfile(folder, '*.txt'));

After choosing the sub-folder manually with uigetdir, the procedure works well. I would like to do all simply by indicating where is the working folder with one push-button.

I am guessing that should be something like

folder_destination1 = folder,'power';
files1 = dir(fullfile(folder_destination1, '*.txt'));

folder_destination1 = folder,'power'; files2 = dir(fullfile(folder_destination2, '*.txt'));

How to update the folder name by updating with the sub-folder name?

Thanks in advance

I found the answer. Cheers

folder = uigetdir('C:\Users\...\working folder');

folder_sub1 = fullfile(folder,'power');
folder_sub2 = fullfile(folder,'thickness');

files1 = dir(fullfile(folder_sub1, '*.txt')); 

files2= dir(fullfile(folder_sub2, '*.txt'));

@ARP: simpler:

workpath = uigetdir('C:\Users\...\working folder');
files1 = dir(fullfile(workpath,'power','*.txt'));
files2 = dir(fullfile(workpath,'thickness','*.txt'));

You can get the path of the working folder by using fileparts:

[workpath,subfolder] = fileparts(folder)

Once you have the working path then you generate the subfolder path easily:

fullfile(workpath,'power','*.txt')
fullfile(workpath,'thickness','*.txt')

Thanks but is not working. The idea is to select the working folder with uigetdir.

There should be instructions to open automatically the sub-folder called "power" and "thickness".

It would continue as:

NF1 = length(files1); 

for i = 1:NF1

       B1=import_AB_function(fullfile(folder1,files1(i).name));  

       t1{i} = B1; 

       Time_R1 = (t{:, i}(:,1));
       Ampl_R1 = (t{:, i}(:,end));

end

NF2 = length(files2); 

    for i = 1:NF2

         B2=import_AB_function(fullfile(folder2,files2(i).name));  

         t2{i} = B2; 

         Time_R2 = (t{:, i}(:,1));
         Ampl_R2 = (t{:, i}(:,end));

    end

"The idea is to select the working folder with uigetdir."

Sure, like this:

workpath = uigetdir(...);

"There should be instructions to open automatically the sub-folder called "power" and "thickness"."

I don't know what you mean by "open" a folder: MATLAB is not an application that "opens" folders. But if you mean that you want to read/write files from those folders, then the code I gave in my answer will help you:

S = dir(fullfile(workpath,'power','*.txt'))
N = numel(S);
C = cell(1,N);
for k = 1:N
    F = fullfile(workpath,'power',S(k).name);
    C{k} = load_your_data(F);
end

and the same for 'thickness'. Note that fullfile accepts more than two input arguments.
