BlueHarvest 7.2.1 | Mac OS X | 9 MB. 

BlueHarvest is an exterminator for your Mac's unnecessary Desktop Service Store (DS_Store) and resource fork (_AppleDouble) files.
Whether you manage a version control system or just want to maximize your available memory, DS_Store and _AppleDouble files are a nuisance. Get BlueHarvest, and give those superfluous files the boot. 

A clean Mac is a happy Mac
Keep it clean. Blue Harvest does more than remove existing files -- it blocks new ones from being created. 
Easy interface. With BlueHarvest, a less cluttered Mac is only two clicks away. 
Instant access. Want to clean up a folder without launching BlueHarvest? Simply control-click.

Compatibility: OS X 10.10 or later 64 bit
