Very interesting replies, thank you very much. I don't want to load
the whole file into memory, the main, virtual or whatever, but I do
want to have an access to it. The C runtime fopen() gives me a handle
to my big file (and to the biggest files on my harddisk, which are now
a couple of HD films). Then I can read from it with a trivial C code.
Why can't I do the same from Mathematica?
In[3]:= snum = OpenRead["scandata.xyz"]
Out[3]= InputStream["scandata.xyz", 29]
In[4]:= FileByteCount["scandata.xyz"]
Out[4]= -936210076
In[5]:= ReadList[snum, Number, 3]
Out[5]= {}
