Have 25 files in a folder each having around 1,000,000 rows. And want to have one text file having all the data i.e. 25,000,000 rows.

The old fashion DOS command copy could do the task. You can also call it in MATLAB using system(). The trick is the "+" symbol.
system('copy test1.txt+test2.txt+test3.txt test.txt')
As long as there is a carriage return at the end of each text file, the concatenate looks right.
