I have two file with the same name, but different location, for example:
file1: D:/test/abc.m
file2: E:/test/abc.m
one of them has been updated. I could check the last modified name by:
filenames1=dir'(D:/test/);
time_file1=filenames(3).date;
filenames2=dir'(E:/test/);
time_file2=filenames(3).date;
the 'time_file1' and 'time_file2' represents the last modified time of these two files, the format is like: '22-Jan-2019 08:43:06'
my question is:
is there anyway to know which is ealier/later, so that I can keep the latest one for use, with out left-click, then property, to look at.
Bests,
Yu

It might be easier to use the datenum field instead if you simply want to compare dates:
filenames1=dir'(D:/test/);
time_file1=filenames(3).datenum;
filenames2=dir'(E:/test/);
time_file2=filenames(3).datenum;
datediff = time_file1 - time_file2;

Hi:
Thanks for your reply.
one point can not assure the judgement is right. I think knowing the internal method of how these two translate between each other would be more reasonable.
I'm contacting Mathworks Tech Support regarding it, and will come back here after I receive a appropriate solution.
Bests,

[~,Data] = dos('dir D:/test/abc.m');
Scanned_data = textscan(Data,'%s');
Date_modified = Scanned_data{1}{15};
