import a certain text file .txt from a specific folder

I want to import a certain text file .txt from a specific folder.

In case the .txt file is saved in the current folder I open it this way:

import_txt = importdata('name of file.txt');

In my case I proceeded in this way but it is not the correct solution:

folder = 'C:\Users\Alberto\....'; % folder where the .txt file is located.
import_txt = importdata('name of file.txt', folder);

You can try the fullfile function.

Something like this should work:

folder = 'C:\Users\Alberto\....'; % folder where the .txt file is located.
filename = fullfile(folder, 'name of file.txt');
import_txt = importdata(filename);

hello again

for numerical arrays use readmatrix instead of importdata

folder = 'C:\Users\Alberto\....'; % folder where the .txt file is located.
import_txt = importdata(fullfile(folder, 'file.txt')); % or readmatrix
