Whether this is possible and how much effort it is depends a lot on what
the data in that file is. If it is mostly numbers you might have a
chance to read it at chunks and save the data in a binary format. Will
you really need to import all the data or just a part of it?
If your colleague has succesfully converted it to a binary file, why not
try if you can import from that format? Mathematica can import .mat
files for example. How large is the binary file he has created?

I think you will need to supply much more details to get any useful help
on this...
