I have a list of structures in a structure.
I tried this:
%% Load data
matpath = 'C:\Users\..;
mydata = dir(fullfile(matpath ,'*.mat'));
full_file_names = fullfile(matpath,{mydata.name});
for n = 1:length(mydata)
mydata(n).data = load(full_file_names{n});
active_flow(n) = mydata(n).data;
end
The mydata(n) structure is ordered. To access of the structure I tried "active_flow(n) = mydata(n).data". But my active_flow is NOT longer ordered.
Please how can sort "active_flow" structure. See an attached screenshot of mydata structure.

"The mydata(n) structure is ordered... But my active_flow is NOT longer ordered."
There is nothing in the code that you show that changes the order.

It is unclear what the problem is, because you did not explain or show either the "wrong" order nor the "right" order. If you want the filenames in alpha-numeric order then you could DOWNLOAD the function NATSORTFILES:
https://www.mathworks.com/matlabcentral/fileexchange/47434-natural-order-filename-sort
P = 'C:\Users\..';
S = dir(fullfile(P,'*.mat'));
S = natsortfiles(S); % DOWNLOAD if you want alpha-numeric order of filenames
for n = 1:numel(S)
F = fullfile(S(n).folder,S(n).name);
S(n).data = load(F);
end
active_flow = [S.data] % optional, if all MAT files contain the same variable names

"which folder the function suppose to be in?"
It is exactly as with your own files: either in the current directory (simpler) or on the MATLAB Search Path:
