.GROWLREGDICT File Extension

Temporary file created by Growl, an application notification program for Mac OS X; stores information used by the Growl Dictionary (GrowlDict).

Growl temp files typically are named "Growl-[long string of characters].growlRegDict." In Growl v.6, they may show up in the Trash in a "Recovered Files" folder and can be deleted by the user. Growl v.7 appears to fix this problem.
