How to convert Word Document files into plain-text files

In order to use the contents of a Word Document (“.doc” or “.docx” extension) in a concordancer it must be converted or saved as a plain text file (“.txt” extension). I will outline two different ways you can do this below.

Method 1 (recommended)

  1. open the document in Word,
  2. do a “select all” (ctrl+A),
  3. “copy” (ctrl+C),
  4. open Notepad (found in Start > All Programs > Accessories),
  5. “paste” (ctrl+V) the content into Notepad,
  6. save the file

Method 2

  1. open the document in Word,
  2. do a “Save as” in Word (goto File > Save as),
  3. select “Save as type” (see image) as “plain text”,
  4. click “Save”,
  5. when the dialogue box appears (for non-English OSs) check “allow character substitution” and then click “OK”


IDC: Windows Phone will reach double-digit market share… in 2017

I’m sure microsoft could…


Although it seems that Microsoft has beaten BlackBerry in the battle for third place in the global smartphone market, the company may not be too thrilled with the prize that it’s won. The latest projections from research firm IDC predict that Windows Phone won’t reach a double-digit share of the global smartphone market until 2017, when it will account for 10.2% of all smartphones shipped. IDC projects that iOS will increase its market share slightly between now and 2017, when it will account for just under 17.9% of all smartphones. IDC also sees Android remaining the dominant mobile OS in 2017, although its market share is projected to slip from 75.3% in 2013 to 68.3% in 2017.
