My question is about automatic calculate the total of images in a folder, i used the coding provided by Mr./Mrs/Miss Image Analyst and it works. Now i faced another problem is that i will have new folder for everyday, so how can i make it to automatic calculate the total of images in the folder everyday.

Try something like this:

filePattern = fullfile(yourFolder, '*.spm');
files = dir(filePattern);
numberOfFiles = length(files);
message = sprintf('Total number of spm files = %d', numberOfFiles);
set(handles.text1, 'String', message);

yea i do my searching on datenum, currently i just able to get the date and time of computer and play with deduction or subtraction of day, i still havent figure out how to get the modified date of files..

datenow = datestr(clock,0);
dateNowNum = datenum(datenow);
date12hrsBe4r = datestr(dateNowNum-0.50);

this just for finding current time and the time of 12 hours ago..i wanted to make it as a range and calculate how many files which their date and time are within this range, but i still have no idea on how to write the codings, do you still have any suggestion?
