Hi,
Please see the code below I used to extract the information from the folder. So the folder has 28 sub-folder with the name "Run 12-27-56.Adaptive PIV.6uqqm6yu", and so on. I want to plot on X-axis number of floder like 1,2,,3,4,5,6....28 and on y-axis corresponding file name (only the number part for example 12-27-56) which is a timestamp actually. Can you help, I am posting the code and result below.
Code:
close all; clear all; clc
%Location of the directory
Location = 'F:\3-PIV_Experimental_Data\Outlet_110\Data_LaserSheet_A\Data_Vector_Masked';
% Get a list of all files and folders in this folder.
files = dir(Location);
% Get a logical vector that tells which is a directory.
dirFlags = [files.isdir];
% Extract only those that are directories.
subFolders = files(dirFlags); % A structure with extra info.
% Get only the folder names into a cell array.
subFolderNames = {subFolders(3:end).name} % Start at 3 to skip . and ..
%Print folder names to command window.
for k = 1 : length(subFolderNames)
fprintf('Sub folder #%d = %s\n', k, subFolderNames{k});
end
Results:
Sub folder #1 = Run 12-27-56.Adaptive PIV.6uqqm6yu
Sub folder #2 = Run 12-28-48.Adaptive PIV.6uqqlrqv
Sub folder #3 = Run 12-29-46.Adaptive PIV.6uqqlgku
Sub folder #4 = Run 12-30-23.Adaptive PIV.6uqql4fz
Sub folder #5 = Run 12-31-15.Adaptive PIV.6uqqkre7
Sub folder #6 = Run 12-31-50.Adaptive PIV.6uqqkfgv
Sub folder #7 = Run 12-32-25.Adaptive PIV.6uqqk3d3
Sub folder #8 = Run 12-33-17.Adaptive PIV.6uqqjqh2
Sub folder #9 = Run 12-33-54.Adaptive PIV.6uqqjctq
Sub folder #10 = Run 12-34-27.Adaptive PIV.6uqqiyst
Sub folder #11 = Run 12-35-04.Adaptive PIV.6uqqip1p
Sub folder #12 = Run 12-36-17.Adaptive PIV.6uqqidrr
Sub folder #13 = Run 12-36-47.Adaptive PIV.6uqqi25r
Sub folder #14 = Run 12-37-21.Adaptive PIV.6uqqhnwu
Sub folder #15 = Run 12-37-58.Adaptive PIV.6uqqhcsl
Sub folder #16 = Run 12-38-37.Adaptive PIV.6uqqh0on
Sub folder #17 = Run 12-39-27.Adaptive PIV.6uqqgp8m
Sub folder #18 = Run 12-40-01.Adaptive PIV.6uqqgdqt
Sub folder #19 = Run 12-40-36.Adaptive PIV.6uqqg1kn
Sub folder #20 = Run 12-41-11.Adaptive PIV.6uqqfpie
Sub folder #21 = Run 12-42-03.Adaptive PIV.6uqqfco7
Sub folder #22 = Run 12-43-07.Adaptive PIV.6uqqf0sv
Sub folder #23 = Run 12-43-59.Adaptive PIV.6uqqenyl
Sub folder #24 = Run 12-44-36.Adaptive PIV.6uqqdwdb
Sub folder #25 = Run 12-45-16.Adaptive PIV.6uqqdkcu
Sub folder #26 = Run 12-45-51.Adaptive PIV.6uqqd6wt

I would suggest converting the extracted timestamps to durations. Then you can just plot it. The x value will be the index number of the timestamp (1, 2, 3, ...) and the y value will be the time, formatted as a time.
It takes a little manipulation to get things formatted correctly, but not a lot of code.
subFolderNames(1) = "Run 12-27-56.Adaptive PIV.6uqqm6yu";
subFolderNames(2) = "Run 12-28-48.Adaptive PIV.6uqqlrqv";
subFolderNames(3) = "Run 12-29-46.Adaptive PIV.6uqqlgku";
subFolderNames(4) = "Run 12-30-23.Adaptive PIV.6uqql4fz";
subFolderNames(5) = "Run 12-31-15.Adaptive PIV.6uqqkre7";
subFolderNames(6) = "Run 12-31-50.Adaptive PIV.6uqqkfgv";
subFolderNames(7) = "Run 12-32-25.Adaptive PIV.6uqqk3d3";
subFolderNames(8) = "Run 12-33-17.Adaptive PIV.6uqqjqh2";
subFolderNames(9) = "Run 12-33-54.Adaptive PIV.6uqqjctq";
subFolderNames(10) = "Run 12-34-27.Adaptive PIV.6uqqiyst";
subFolderNames(11) = "Run 12-35-04.Adaptive PIV.6uqqip1p";
subFolderNames(12) = "Run 12-36-17.Adaptive PIV.6uqqidrr";
subFolderNames(13) = "Run 12-36-47.Adaptive PIV.6uqqi25r";
subFolderNames(14) = "Run 12-37-21.Adaptive PIV.6uqqhnwu";
subFolderNames(15) = "Run 12-37-58.Adaptive PIV.6uqqhcsl";
subFolderNames(16) = "Run 12-38-37.Adaptive PIV.6uqqh0on";
subFolderNames(17) = "Run 12-39-27.Adaptive PIV.6uqqgp8m";
subFolderNames(18) = "Run 12-40-01.Adaptive PIV.6uqqgdqt";
subFolderNames(19) = "Run 12-40-36.Adaptive PIV.6uqqg1kn";
subFolderNames(20) = "Run 12-41-11.Adaptive PIV.6uqqfpie";
subFolderNames(21) = "Run 12-42-03.Adaptive PIV.6uqqfco7";
subFolderNames(22) = "Run 12-43-07.Adaptive PIV.6uqqf0sv";

subFolderNames(25) = "Run 12-45-16.Adaptive PIV.6uqqdkcu";
subFolderNames(26) = "Run 12-45-51.Adaptive PIV.6uqqd6wt";
dates = extractBetween(subFolderNames,"Run ",".");
dates = replace(dates,'-',':');
dates = duration(dates,"InputFormat","hh:mm:ss")
dates = 1×26 duration array
12:27:56 12:28:48 12:29:46 12:30:23 12:31:15 12:31:50 12:32:25 12:33:17 12:33:54 12:34:27 12:35:04 12:36:17 12:36:47 12:37:21 12:37:58 12:38:37 12:39:27 12:40:01 12:40:36 12:41:11 12:42:03 12:43:07 12:43:59 12:44:36 12:45:16 12:45:51

I used the help documentaton for MATLAB. Go there and then just search for each of the functions I used.

Here is something you can try:
close all; clear all; clc
%Location of the directory
Location = 'F:\3-PIV_Experimental_Data\Outlet_110\Data_LaserSheet_A\Data_Vector_Masked';
% Get a list of all files and folders in this folder.
files = dir(Location);
% Get a logical vector that tells which is a directory.
dirFlags = [files.isdir];
% Extract only those that are directories.
subFolders = files(dirFlags); % A structure with extra info.
% Get only the folder names into a cell array.
subFolderNames = {subFolders(3:end).name} % Start at 3 to skip . and ..
timeStamps = regexp(subFolderNames,'(\d+)-(\d+)-(\d+)','tokens');
timeStamps = vertcat(timeStamps{:});
timeStamps = cellfun(@str2double,vertcat(timeStamps{:}));
date_of_year = [2022 1 14];
y = datetime( ...
date_of_year(1),date_of_year(2),date_of_year(3), ...
timeStamps(:,1),timeStamps(:,2),timeStamps(:,3));
plot(1:numel(subFolderNames),y);
