how to import 2gb txt file data into workspace?

The txt file has four columns, 8812616 rows , all of which are pure numbers, are 2gb. The content of the file is on the photo.

I try to use textscan but error using textscan.

too many output arguments.

You'd have to post how you were calling textscan for anyone to know why it was wrong.

Also, ~35 characters x 8.8M lines should be around 300MB (assuming 8-bit encoding). Why is the file ~6x larger than expected? Is that any potential source of problems?
