Hi, > I have a 4Gb txt file and it is not possible to work with that > because it is huge. Does someone knows how to convert an ascii file > to a binary file using mathematica?

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? > Your help would be extremelly appreciated. I think you will need to supply much more details to get any useful help on this... albert
