The OS X Finder <a href="http://osxdaily.com/2012/04/17/find-large-files-in-mac-os-x-search/">Search feature can be used to find large files</a> but if you’re really serious about managing disk space and tracking down unnecessary large files and folders, you should use a free tool called OmniDiskSweeper. </p> <p>OmniDiskSweeper is an excellent application for Mac OS X that shows everything on a hard disk in descending order by size, each directory can then be drilled down into further to quickly locate the largest files, and the offending folders or files can be deleted directly from the app. Finding the large files and folders with OmniDiskSweeper is quick and painless:</p> <ol> <li><a href="http://www.omnigroup.com/products/omnidisksweeper/">Download OmniDiskSweeper</a> (free), copy it to your /Applications/ folder, and launch the app</li> <li>Click on your primary hard disk, typically labeled “Macintosh HD”</li> <li>Let OmniDiskSweeper sweep the drive to find all files by size, then click on the topmost directories to find items that can be deleted</li> </ol> <p><em><strong>Important</strong>:</em> OmniDiskSweeper is intended for users who are knowledgable about their Mac file system. If you don’t absolutely know what a file or directory is and if it’s necessary or not, <em>do not delete it</em>! There is no going back, and if you accidentally delete important system files or folders you may find yourself having to recover from a backup or reinstalling OS X. You’ve been warned.</p> <p>Exactly what can be removed is going to vary per user and per drive, but everyone will certainly find items that are no longer necessary to keep around. For example, sweeping my drive with OmniDiskSweeper I discovered and removed the following items:</p> <ul> <li>The user ~/Library/Application Support/ directory contained 1GB of files for apps that are no longer used</li> <li>Spotify Caches were taking up 1GB of disk space, removing that and <a href="http://osxdaily.com/2011/12/08/delete-user-caches-in-mac-os-x/">deleting unnecessary user caches</a> recovered 2GB of disk space immediately</li> <li>Over 1GB of unused OS X Voices were removed</li> <li>The <a href="http://osxdaily.com/2011/03/23/reclaim-disk-space-mac-delete-downloads-folder/">Downloads folder has become enormous</a>, deleting everything from there recovered a quick 4GB</li> <li>900MB of unused and long forgotten Applications were <a href="http://osxdaily.com/2011/06/20/uninstall-mac-applications/">uninstalled</a> freeing up space</li> </ul> <p>Ultimately how much all this matters and how much disk space you need to reclaim is going to depend on the capacity of a Mac hard drive. I use a MacBook Air 11″ with only a 64GB SSD making each 1GB of unnecessary files or folders significant, and I was able to quickly recover about 12% of total disk capacity just by looking through OmniDiskSweeper and removing what I know isn’t needed. </p> <p>Consider adding OmniDiskSweeper to <a href="http://osxdaily.com/2012/03/04/mac-maintenance-tips/">part of a general Mac maintenance routine</a>, even those with very large hard drives will find it to be an effective method of keeping a file system under control. </p> </div> <p><a href="http://feedads.g.doubleclick.net/~a/cgHeD9e4lNHL-5PXmv4ceMuuTzE/0/da"><img src="http://feedads.g.doubleclick.net/~a/cgHeD9e4lNHL-5PXmv4ceMuuTzE/0/di" border="0" ismap="true"></img></a><br/> <a href="http://feedads.g.doubleclick.net/~a/cgHeD9e4lNHL-5PXmv4ceMuuTzE/1/da"><img src="http://feedads.g.doubleclick.net/~a/cgHeD9e4lNHL-5PXmv4ceMuuTzE/1/di" border="0" ismap="true"></img></a></p><div class="feedflare"> <a href="http://feeds.feedburner.com/~ff/osxdaily?a=HBGG_XLKcHU:i-TosHhU19k:yIl2AUoC8zA"><img src="http://feeds.feedburner.com/~ff/osxdaily?d=yIl2AUoC8zA" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/osxdaily?a=HBGG_XLKcHU:i-TosHhU19k:V_sGLiPBpWU"><img src="http://feeds.feedburner.com/~ff/osxdaily?i=HBGG_XLKcHU:i-TosHhU19k:V_sGLiPBpWU" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/osxdaily?a=HBGG_XLKcHU:i-TosHhU19k:D7DqB2pKExk"><img src="http://feeds.feedburner.com/~ff/osxdaily?i=HBGG_XLKcHU:i-TosHhU19k:D7DqB2pKExk" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/osxdaily?a=HBGG_XLKcHU:i-TosHhU19k:7Q72WNTAKBA"><img src="http://feeds.feedburner.com/~ff/osxdaily?d=7Q72WNTAKBA" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/osxdaily?a=HBGG_XLKcHU:i-TosHhU19k:qj6IDK7rITs"><img src="http://feeds.feedburner.com/~ff/osxdaily?d=qj6IDK7rITs" border="0"></img></a> </div><img src="http://feeds.feedburner.com/~r/osxdaily/~4/HBGG_XLKcHU" height="1" width="1"/> View the full article
