Temporary Internet files are automatically saved to hard disk to speed up the display of frequently visited Web pages. Internet Explorer saves the files in the Temporary Internet Files folder, which can contain cookies, graphics, Web pages, and JavaScript files, among other things. Because Internet Explorer can open files saved to the com puter faster than it can obtain and open files from the Internet, maintaining the files in this folder is quite important to successful, fast Web browsing. However, problems occur when the Temporary Internet Pages cache is full. Resolving these problems is as simple as deleting the files in the Temporary Internet Files folder. Unfortunately, recognizing problems caused by a full Temporary Internet Files folder can be difficult. Here are some common warning signs of a full Temporary Internet Files folder:

An end user reports he cannot use the Save Picture As command to save a graph ics file to his hard disk as a .jpeg or .gif, but the file can be saved as a .bmp file. The file name might also appear as Untitled. An end user reports problems viewing History files by date, or no data appears. An end user reports that when he selects Source on the View menu to view the source for a Web page, the source code does not appear as expected. An end user reports that when he visits the Windows Update Product Catalog website, he receives the message Cannot Display Page. (This happens because the user has an earlier version of the site control in his or her browser cache and the cache is full.) An end user reports that he gets unrecoverable errors (faults) when using Internet Explorer.

Supporting Microsoft Internet Explorer
Although these problems can occur for other reasons, deleting the files in the Tempo rary Internet Files folder often solves the problem. In the next few sections, you learn several ways to manage and delete temporary Internet files.
Using Disk Cleanup
Disk Cleanup is a maintenance tool that is included with Windows XP. You can use Disk Cleanup to resolve problems, but you can also teach your end users to use it to maintain their computers on their own. Disk Cleanup deletes files in the Downloaded Program Files folder, the Temporary Internet Files folder, the Temporary Files folder, the Recycle Bin, and more. Deleting these files regularly helps keep the com puter running smoothly.
Deleting Files With Disk Cleanup To use Disk Cleanup, follow these steps: 1. From the Start menu, point to All Programs, point to Accessories, point to System Tools, and select Disk Cleanup. 2. In the Select Drive dialog box, select the drive to clean up from the Drives dropdown list, and click OK. 3. In the Disk Cleanup dialog box, shown in Figure 5-7, select the folders and the items to clean up. You can read a description of what is in each folder by clicking it once.

4. To view any of the files, click View Files. 5. Click OK to start the cleaning process. Click Yes to verify that you want to perform these actions.
Note
Urge your end users to use Disk Cleanup at least once a month.
Real World
Reclaiming Wasted Space
Disk Cleanup can help free up disk space by deleting common temporary files found in various locations across your hard drive. However, the space reclaimed using Disk Cleanup is usually not very much by today s standards. A crowded disk can slow the responsiveness of Windows and running applications, includ ing Internet Explorer. Here are some other ways you can help users free up disk space:
Remove unused applications. Use Add Or Remove Programs in Control Panel to see all the applications installed on the system. Scan for any appli cations that users do not need anymore. (Always check with the user before removing applications, of course.) There may even be applications the user does not know about. Archive old or large documents. If the user has a CD or DVD writer, con sider archiving older documents to disk to free up disk space. If there are especially large documents (such as videos), consider moving those to disk as well. Teach users to use the tools described in 3 to perform routine mainte nance on their hard disks. These tools include Check Disk and Defragmenter. Use Disk Compression to compress documents so that they take up less space.
