Windows offers a tool to help you purge files you may no longer need and might not otherwise be able to locate. The Disk Cleanup utility locates files that can easily be removed to free up some disk space. To run this utility, obey these directions:
  1. Tap the Windows key.
  2. Type disk cleanup.
  3. Choose the Disk Cleanup Desktop app from the search results.
  4. Choose the mass storage device that you want to clean up. This prompt appears only when you have multiple storage media on your PC. You probably want to choose drive C, the main storage device, which is already chosen for you.

    The Disk Cleanup utility scans the media, looking for useless files. When it's done, you see the Disk Cleanup dialog box, as shown.

  5. Place check marks by all the items. Seriously, nothing listed in the dialog box is of any consequence to you, yet the Disk Cleanup utility leaves several items unchecked, probably just to give you something to do.
  6. Click OK.
  7. Click the Delete Files button to confirm and begin the cleanup process. Wait while the files are removed. When the process is complete, the window goes away.

For even more aggressive file purging, click the Clean Up System Files button. The Disk Cleanup utility starts over again, but this time it lists various unneeded bits and pieces of Windows.

• Check the media's before‐and‐after size when you run the Disk Cleanup utility. That's the best way to gauge how successful you are in increasing media capacity. • You can also access the Disk Cleanup utility from a drive's Properties dialog box: Click the Disk Cleanup button on the General tab. • Rarely will you use Disk Cleanup and have it fix the problem of a crowded hard drive, so you may share some disappointment in its performance. Use this tool in combination with others to help improve storage capacity.

About the book author:

Dan Gookin has been writing about technology for 20 years. He has contributed articles to numerous high-tech magazines and written more than 90 books about personal computing technology, many of them accurate.
He combines his love of writing with his interest in technology to create books that are informative and entertaining, but not boring. Having sold more than 14 million titles translated into more than 30 languages, Dan can attest that his method of crafting computer tomes does seem to work.
Perhaps Dan’s most famous title is the original DOS For Dummies, published in 1991. It became the world’s fastest-selling computer book, at one time moving more copies per week than the New York Times number-one best seller (although, because it’s a reference book, it could not be listed on the NYT best seller list). That book spawned the entire line of For Dummies books, which remains a publishing phenomenon to this day.
Dan’s most recent titles include PCs For Dummies, 9th Edition; Buying a Computer For Dummies, 2005 Edition; Troubleshooting Your PC For Dummies; Dan Gookin’s Naked Windows XP; and Dan Gookin’s Naked Office. He publishes a free weekly computer newsletter, “Weekly Wambooli Salad,” and also maintains the vast and helpful Web site www.wambooli.com.
