Excellent work choroba! On my machine I see: 

get properties: 17 secs
sort + output: 18 secs
total: 35 secs

[download]
more than twice as fast as my original Perl version of 85 secs ... with Windows Private Bytes increasing from 2,236,648K to 3,516,476K.

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
