Maximum file size

I'm trying to analyze the results of a long calculation (5500 time steps of a finite difference calc on a 90 x 90 x 21 mesh). The data are in an external file, but when I even try to read part of it, Mathematica seems to take one look and curl up into the fetal position: In[24]:= fid = OpenRead[saveFilename, BinaryFormat -> True] BinaryRead[fid, "Real32"] Close[fid] Out[24]= InputStream["video1_100407-c.solv", 35] Out[25]= EndOfFile Out[26]= "video1_100407-c.solv" I know the file is good because I can still get at it using other tools. Most likely I'll throw together an external program that will take the filename and re-write a subset of the data to a new, temporary file. So my question is - does anyone know if there's a maximum size beyond which Mathematica will not even attempt to read from a file? Given my results, I suspect the answer is "yes," so does anyone know what that limit is? If the answer is actually "no," then I'd be very interested in knowing what I'm doing wrong. Thanks, Greg
