problem with sorting a structure

I have a structure created by the dir command so I have something like that
images=dir('file*.tif')
The problem is that the struct created has its names that go like this
file1.tif
file10.tif
file2.tif
file20.tif
I want to sort all the contents of the struct so that it'll go like
file1.txt
file2.txt
file3.txt
...
file10.txt
But I want to do it without using cells. Just to sort the structure. Is there a way to do so?

images=dir('file*.tif');
n = {images.name}';
[~,ii] = sort(str2double(regexp(n,'(?<=file)\d*(?=\.txt)','match','once')));
images = images(ii);

Try this once and let me know:
clc; clear all ;
f=dir('file*.txt') ; % get txt files in the folder
nfiles = length(f) ; % total number of files
iwant = zeros(nfiles,1) ; % numbers at the end of files
for i = 1:nfiles
B = regexp(f(i).name,'\d*','Match'); % get the number at the end of file
iwant(i) = str2num(B{1}) ;
end
%%Sort the numbers iwant
[val,idx] = sort(iwant) ; % sorting the numbers
sort_f = f(idx) ;
