Pat,

I am unfamiliar with the use of the word "junk" as a unit of measure for data objects. I figure there are a few different possibilities:

  1. You are using the term intentionally meaning that you suggest he increases the size in terms of old cars and broken pianos rather than used up pens and broken pencils.
  2. This was a Freudian slip based on your opinion of some datasets you have seen.
  3. Somewhere between your mind and the final product "jumps/chunks" became "junks" (possibly a microsoft "correction", or just typing too fast combined with number 2).
  4. "junks" is an official measure of data/object size that I need to learn more about (the history of the term possibly being related to 2 and 3 above).

Please let it be #4, I would love to be able to tell some clients that I have received a junk of data from them.
