MATLAB: Dir function and importing data

dirfopenimport

Hey guys,
I have a folder called 'KR5' filled with 100 notepad files. Each notepad file has lots of data that I want. I want to read the data from each file and store it.
Here is my approach:
Using a for loop, read and store all of notepad file names into a variable "Direc".
Using another for loop, open each file and extract the data and store it. Here is the code I have so far:
clc;
clear all;
addpath(genpath(pwd));
Direc = dir('KR5');
for i = 1:length(Direc)
    Direcname(i) = Direc(i).name;
end
I am getting this error:
??? In an assignment A(:) = B, the number of elements in A and B must be the same.
Can someone help me with this?

Direc(1).name is a [1 x N] char vector, also called a "string". You try to assign it to the scalar Direcname(1). But you cannot store a vector in a scalar.
You can store string in a cell:
...
Direcname{i} = Direc(i).name;
...
Consider the curly braces.
The loop can be omitted:
Direc     = dir('KR5');
Direcname = {Direc(i).name};
Btw. clear all deletes all loaded functions from the memory. This does not have any advantage, but the reloading needs a lot of time. clc is not helpful here also.
Adding the current folder and all subfolders to the Matlab path might be useful for any purpose, but for the shown problem it does not help. Better use the absolute path of "KR5", see help fullfile.
