Problem with file text size in bytes

in GUI MATLAB HOW I CAN FIND THE SIZE OF THE FILE TEXT AFTER IMPORT THIS FILE BY THIS CODE :

 [file,path] = uigetfile('*.txt','Select file');
var=strcat(file,path);
file=dlmread(var);

------------------------------

and i used this code to read the file text

[filename,pathname] = uiputfile( ...
{'*.txt','save as'});
var=strcat(pathname,filename);
dlmwrite(var,x);

hi, what do u mean by size. size of the file in bytes or size of the filename?

I Mean in bytes .

@wissa amer: It is recommended to avoid using "path" as name of a variable, because this is an important Matlab command. Such a shadowing can cause serious troubles during debugging. The same concerns to "var", which calculates the variance.

Instead of var=strcat(file,path) the function fullfile is safer:

[fileName, pathName] = uigetfile('*.txt','Select file');
file = fullFile(pathName, fileName);  % Swapped arguments!

[Chandrasekhar]

use the command

a= dir('complete path of the file')

example: F:\Matlab\text.txt

It gives a structure with bytes as one of the field

i can not do this in my GUI

[Chandrasekhar]

Could you plz tell me how your GUI looks like and what are u trying to do frm your GUI

[Walter Roberson]

What happens when you try to do it in your GUI?

Explicitly:

dirList  = dir(fullfile(pathName, fileName));
fileSize = dirList.bytes;
