Deleting Unnecessary Files
If you find that a hard disk partition is getting low on free space, you should delete any unneeded files and programs. Windows Vista comes with a Disk Cleanup utility that enables you to remove certain types of files quickly and easily. Before discussing this utility, let's look at a few methods you can use to perform a spring cleaning on your hard disk by hand:
- Uninstall programs you don't use— If you have an Internet connection, you know it's easier than ever to download new software for a trial run. Unfortunately, that also means it's easier than ever to have unused programs cluttering your hard disk. Use the Control Panel's Add or Remove Programs icon to uninstall these and other rejected applications.
- Delete downloaded program archives— Speaking of program downloads, your hard disk is also probably littered with ZIP files or other downloaded archives. For those programs you use, you should consider moving the archive files to a removable medium for storage. For programs you don't use, you should delete the archive files.
- Archive documents you don't need very often— Our hard drives are stuffed with ancient documents that we use only rarely, if at all: old projects, business records from days gone by, photos and videos from occasions held long ago, and so on. You probably don't want to delete any of this, but you can free up hard disk space by archiving those old documents to removable media such as recordable CD or DVD disks, or a flash drive.
- Remove Windows Vista components that you don't use— If you don't use some Windows Vista components, remove them from your system. To do this, select Start, Control Panel, Programs, Turn Windows Features On or Off. Enter your UAC credentials to see the Windows Features dialog box. Deactivate the check box for each feature you don't use, and then click OK.
- Delete application backup files— Applications often create backup copies of existing files and name the backups using either the bak or .old extension. Use Windows Explorer's Search utility to locate these files and delete them.
After you've performed these tasks, you should next run the Disk Cleanup utility, which can automatically remove some of the preceding file categories, as well as several other types of files, including downloaded programs, Internet Explorer cache files, the hibernation files, Recycle Bin deletions, temporary files, file system thumbnails, and offline files. Here's how it works:
- Select Start, All Programs, Accessories, System Tools, Disk Cleanup. The Disk Cleanup Options dialog box appears.
- Click one of the following options and then enter your UAC credentials when prompted:
- My Files Only— Click this option to delete only those disposable files that you have generated yourself.
- Files from All Users on This Computer— Click this option to delete disposable files generated by every user on your computer
- In the Drive Selection dialog box that appears, select the disk drive you want to work with and then click OK. Disk Cleanup scans the drive to see which files can be deleted, and then displays a window similar to the one in Figure 15.6.
Figure 15.6 Disk Cleanup can automatically and safely remove certain types of files from a disk drive.
- In the Files to Delete list, activate the check box beside each category of file you want to remove. If you're not sure what an item represents, select it and read the text in the Description box. Note, too, that for most of these items you can click View Files to see what you'll be deleting.
- Click OK. Disk Cleanup asks whether you're sure that you want to delete the files.
- Click Yes. Disk Cleanup deletes the selected files.
