OmniDiskSweeper is a powerful Mac OS X tool for quickly finding and deleting big, useless files and thus making space on your hard disks.OmniDiskSweeper makes this easy by highlighting the biggest files on your disks, and by noting which files are used by the system, so you don\'t accidentally delete important files.When you start OmniDiskSweeper, it presents you with a list of disks attached to your machine. Double-click on one, and a new window opens with a \"column\" view listing every folder and file on that disk, which it sorts by size as you watch.You then simply browse through the folders and files and delete the large ones which you are no longer using. If a file is part of the system, it\'ll say so on the panel (in the list of Packages the file belongs to), so you won\'t accidentally delete something that would make your system stop working. The free space on the disk and the ordering of the folders are automatically recalculated. If you aren\'t sure what\'s in a file, you can open it by double-clicking on its icon or dragging its icon onto another application. It\'s that easy!While this concept may seem awfully close to what the Finder does, it\'s actually amazing how much more useful it is for cleaning up your hard disks. Since the directories and files are sorted by size, you get to quickly zoom in on the big files that are taking up all the space and not worry about the thousands of tiny ones that aren\'t hurting anyone.What\'s New in This Release: [ read full changelog ]· Several behind-the-scenes updates to the built-in software update feature, and one very useful new feature: you can now tell software update to ignore a specific update.· Updated OmniDiskSweeper\'s crash catcher to be compatible with Snow Leopard.· New release notes no longer display on launch; they\'re still available from the software update feed, the download page, and the Help menu.
