How to read .txt files named as number?

In one of my folders i have files like "Mech_01.txt", "Mech_02.txt", "Mech_03.txt"......... as well as files like "Mech_A.txt", "Mech_B.txt", "Mech_C.txt"..........

How can i read them separately using dir command?

Flame_speed__Exp_folder = '/home/ali/LFS/test/Test_rig';
Allfiles_Exp = dir(fullfile(Flame_speed__Exp_folder, '*Mech_*.txt'));
