negative FileByteCount


Is there a maximum file size permitted in Mathematica? Because it
seems I can't work with my 3GB file,
In[1]:= FileByteCount["scandata.xyz"]
Out[1]= -936210076

snum = OpenRead["scandata.xyz"]
Read[snum, Number]
Out[]=EndOfFile

If not Mathematica, where should I bring files big like this (which
are xyz point cloud data, need to denoise/detrend, perhaps via a
wavelet decomposition or other multiresolution analysis)
