The best time to register for DrupalCon Dublin is now. Earlybird discounts end July 29.
I use 7-ZIP instead of Win Zip. Is there a way to open Drupal software using the 7-zip?
yes. 7-zip opens both .zip and .tar.gz right on the archive and select extract or double click on it and drag the folder out. See 7-zip documentation for further aid.
