Use WriteString[]. :-)

Even then, however, you won't be able to go through the entire 5.6GB 
file without some additional programming.  Mathematica's 
OpenRead/OpenWrite can't currently access that large of a file.

(This limitation will be addressed in a future version of Mathematica.)

The current workaround is to use Java through JLink.  You will need to 
use java.io.BufferedReader and java.io.FileReader classes. If you're not 
familiar with Java, you can just search online for how to open a file 
for reading with Java.

You can may also contact Wolfram's Technical Support if you need some 
step-by-step assistance.

Regards,

Igor
