Hello,
I have about 30 txt files, each file is about 5GB in size.
these text files are basically huge percause they are not compressed and they contains records line by line like this

name1560
name16598
name89865

I would like to know what would be the best approach to merge all these files into one?

That's going to be a massive file!  

Anyway what I would do is split the files down further so that any reads can manage the load.  Then, read each of the smaller files using a StreamReader and write the contents to a single file using StreamWriter (append true).  

It may struggle somewhat as it gets into the 10's of GB, but I've never had to create a text file so large so I can't confirm that.
