A script to load multiple (n) txt files and save them into a single matrix of n columns

Sorry for disturbing with this basic question, but I am new in MATLAB. I have been using OriginLab for many years. Importing data and copying individual columns into a single large matrix was very easy. It seems like impossible now.
I have a folder with several files, lets say 15, saved as a text file. The text file contains a heading to be removed, starting from row 6. The file itself is simply time and amplitude from the oscilloscope. I need to load the files and paste them into one single matrix. Only first column would be time, the rest are the amplitude data.
Any tips to generate a script to automate that? using the import function does it only for one file. When doing it again overwrites the values.
Thanks in advance

F = dir('*.txt'); % you are in the folder of text files
NF = length(F) ; % number of files
data = cell(N,1) ;
for i = 1:length(F)
thisdata = importdata(F(i).name) ;
% pick your data from here
data{i} = thisdata.data ;
end
Later you can convert your cells into matrix using cell2mat. Or you can initialize, your matrix and kepp adding the column inside the loop.
