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);

@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!

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

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