Absolutely no problem on 64-bit OSes with enough memory.  Many 32-bit OSes 
have problems with > 2Gb files.

Please do read the posting guide and tell us basic facts like which OS you 
are running on, so we don't have to speculate to answer your question.

Also, what you want to do with the dataset?   This matters crucially.
