I believe the size of the files you can open depend on your operating system and file system rather than on C++. For example, I believe that Windows generally doesn't support files larger than 2 GB. I believe most 32-bit Linux distributions also don't generally support files larger than 2GB out of the box. Without knowing what platform and type of file system that you're running on, it's hard to say much more, though.

How would I go about finding out the largest file stream I can open (read/write) on my system (P4)? I've ascertained that the std::fstream::pos_type has a sizeof() 8, but anytime I access somewhere beyond the 2**31-bit mark, the state of the stream becomes good()==false. If the maximum size is upper-bound by the 2**31-bit mark (or whatever), is there anything in the standard libraries to let me open larger files (i.e. a memory-map or sumsuch)?
thanks,
