Hi,
I use this code to load .m file
[filename, pathname] = uigetfile( ...
{'*.m', 'All matlab-Files (*.m)'; ...
'*.*','All Files (*.*)'}, ...
'Select Matlab File');
save(fullfile(pwd, filename));
but! .. when i open it after loading, its content was changed to undefined character like this:
ه3"av خًOتJM.aà„ت?A?GB‰?JKـ2sR‎?sS‹!b?HْYذô3Bظ0s? ü¬ؤ”ش ¨™??ô³ èga?ِwٍ?és  ڈ?ح^?ك%5/?³83/]/?,?
how i can save it with orginal content (matlab code)?

Could you clarify exactly what you want to do? save command saves the workspace variables, not the file. Besides, you already have the file and what's the point to save it again? Do you mean you want to run the script and save the result?

and i put "add new file" button , to add this new file to my list box (and add it to current dirctory too).

I hope you understand what i want,,

To "add it to current directory too", use copyfile()

uigetfile gets the path, not the data. Before saving you need to load your file. Thus, use function load and give it the path obtained from uigetfile. After you load the data into the variable, you can save it using save function. Also, since you have the filename and the pathname, you dont need to use fullfile. The full path can be provided as follows:[ pathname filename ] As far as I understand you are trying to create a bank of addresses and display them in the listbox, as well as save the data to file. For updating your listbox use the fillowing idea:
your code here
....
currentDATA=get(listbox.handles,string);
updatedDATA={currentDATA; pathfile filename};
set(handles.listbox,string,num2str(updatedDATA)); %updates the listbox
save([pathname filename],'updatedDATA'); saves the data to file

correction: most likely, it is handles.listbox
need to use fullfile(pathname,filename)
