title: Loading a large binary file with kdb+ (Q)
body: <p>I have a set of large files (around 2Gb).
  When I attempt to load it (let's assume that correctly):</p>
  
  <pre><code>ctq_table:flip `QTIM`BID`OFR`QSEQ`BIDSIZE`QFRSIZ`OFRSIZ`MODE`EX`MMID!("ijjiiihcs";4 8 8 4 4 4 2 1 4) 1: `:/q/data/Q200405A.BIN
  </code></pre>
  
  <p>It gives back a <code>wsfull</code> error. Kdb+ as far as I know meant to be used for such tasks.</p>
  
  <p>Is there a way to handle big files without running out of memory (like keeping on disk, even if it is slower)?</p>
