Tip: use FULLFILE to join strings into one filepath, rather than SPRINTF or string concatenation.

Replace
{sad([sad.isdir]).name}
with
setdiff({sad([sad.isdir]).name},{'..','.'})

Note that in theory using setdiff() like that could reorder the files. In practice it is unlikely to reorder the files (not impossible though.)

Given that the order returned by DIR is not specified, I don't see how that makes much difference.

Replace
SFN = sorted_cell_array_of_folder_names(i).name ;% extract his name
with
SFN = sorted_cell_array_of_folder_names{i} ;% extract his name

In context the hypothetical reordering of setdiff() is irrelevant anyhow because the nat sort is done right afterwards ;-)

Do you still have
if endsWith(sorted_cell_array_of_folder_names{i}, '.') || endsWith(sorted_cell_array_of_folder_names{i}, '..')
if so then you can remove that test and the continue, since you already filtered out . and ..

I recommend that you rewrite
tifList = ls(sprintf('%s%s%s%s',PF,SFN,'\','*.tif')); % list all jpg files
in terms of dir() and fullfile()
I do not see where you have defined PF ?
Is there a reason you are not using
PF = 'D:\Project\DB1\test';
sad = dir(fullfile(PF, '*', '*.tif'));
cell_array_of_file_names = fullfile({sad.folder}, {sad.name});
and then cell_array_of_file_names would be the complete list of all .tif files that are one folder level down from DB1\test ?

[folders, basenames, ext] = fileparts(cell_array_of_file_names);
G = findgroups(folders);
[~, labels, ~] = fileparts(folders);
Now you for each entry cell_array_of_file_names{K} then its associated label is labels{K} and you can process all members of the same folder by processing
maxG = max(G);
for fidx = 1 : maxG
matches = find(G == fidx);
these_entries = cell_array_of_file_names(matches);
this_label = labels{matches(1)};
%these_entries is a cell array containing only file names
%that are all part of the same folder, and the folder name
%is in this_label

if ispc()
PF = fullfile('D:\Project\DB1\test\', '*', '*.tif');
else
%for demonstration purposes ONLY.
%MATLAB Answers does not have nat_sort installed, so install it
td = tempname;
mkdir(td);
tz = [td '.zip'];
urlwrite('https://www.mathworks.com/matlabcentral/mlc-downloads/downloads/submissions/10959/versions/4/download/zip/sort_nat.zip', tz);
unzip(tz, td)
addpath(td)
%now point us to a directory we know that some tif files are in
PF = fullfile( fileparts(fileparts(which('cameraman.tif'))), '**', '*.tif');
end
sad = dir(PF); % Returns files only
cell_array_of_file_names = fullfile({sad.folder}, {sad.name});
[folders, basenames, ext] = fileparts(cell_array_of_file_names);
G = findgroups(folders);
[~, labels, ~] = fileparts(folders);
Groups = struct();
maxG = max(G);
for fidx = 1 : maxG
matches = find(G == fidx);
these_entries = cell_array_of_file_names(matches);
these_entries = sort_nat( these_entries );
this_label = labels{matches(1)};
%these_entries is a cell array containing only file names
%that are all part of the same folder, and the folder name
%is in this_label
Groups.(this_label) = these_entries;
end
Groups
Groups.(this_label).'
