Disk Cleanup finds and removes unnecessary files on your hard disk to free up disk space and can help your computer run faster. For better maintenance, it is recommended to run Disk Cleanup every so often to help keep junk off your computer.
Like Disk Cleanup, but much better, CCleaner cleans junk and temp files for Windows and most other programs installed in Windows. CCEnhancer is a small tool which adds support for over 270 new programs into the popular program CCleaner. For better maintenance, it is recommended to run CCleaner as often as you like to help keep large amounts of junk off your computer.
1. Run CCleaner with the CCEnhancer add-on (optional) to clean up junk files from your computer.
Delete C:\Windows.old Folder
If you performed a repair install, upgrade install, or custom install without formatting the drive for a clean install and selected to install Windows 7 on the same partition of the previous Windows installation, then you may have a C:\Windows.old folder left over in your new installation. The C:\Windows.old folder contains all folders and files from the previous Windows installation as a backup. Deleting the Windows.old can free up and recover a large amount of space on your system hard drive (Windows 7 drive).
If you performed a repair install or upgrade install, then you may have the C:\$INPLACE.~TR and C:\WINDOWS.~Q folders left over in your new installation. These folders contain the left over files and folders from upgrading your previous OS to Windows 7. Deleting these folders can free up and recover a large amount of space on your system hard drive (Windows 7 drive).
1. Run Disk Cleanup, click on the Clean up system files button, and then check the Files discarded by Windows upgrade box to delete.
Move Files to Folder on Another Drive and Include Folder in a Library
To save hard drive space on your Windows drive, you could do this below to be able to access the files from your libraries with the files actually located (saved) where you like instead. This way you will not have to worry about any potential issues that come with moving user profile or folder locations using OPTION 8 or OPTION 9 below.
A user profile is the main C:\Users\(user-name) folder of a user account that contains all of the account's settings, shortcuts, information, and user folders (ex: My Music) with the files in them. Moving this user profile folder to another hard drive location will free up space on your Windows 7 system hard drive (Windows 7 drive).
If you did not want to move the entire user profile folder (Option 6), then you could move your choice of individual user folders (ex: My Music) of a user account to a new location instead. Moving user folders to another hard drive location will free up space on your Windows 7 system hard drive (Windows 7 drive).
System Restore uses a feature called System Protection to regularly create and save restore points of selected hard disks in your computer. These restore points contain information about registry settings and other system information that Windows 7 uses, but can use quite a bit of hard drive space.
It is not recommended to turn off system protection for your C: system drive (Windows 7 drive) since it is a great tool to easily undo a mistake, for example one that may have crippled Windows 7, by just doing a system restore to go back to a previous restore point of your system dated before the mistake. You could also use previous versions to restore older copies of files and folders.
If you had turned on system protection for other installed hard disks, then you could turn off system protection for them to free up space on them.
Change Amount of Disk Space Usage by System Protection
Since turning off system protection (OPTION 9) for a hard disk is not really a good idea if you wanted to be able to do a system restore or use previous versions for it, you could just change how much maximum space can be used by system protection on each hard disk that you have system protection turned on for.
By default, Windows 7 will allocate 10% of the total space of a hard disk that has system protection turned on for.
Change Amount of Disk Space Usage by Offline Files
When you make a network file, or all files in a network folderavailable offline, Windows 7 Professional, Ultimate, or Enterprise editions will create a copy of the file or folder on your computer so that you can work with them when you're not connected to the network or when the network folder that the files are stored in is not available. This is called an offline file.
You can change the maximum hard disk space usage limit for these offline files to prevent to much space to be used on a hard disk.
When the final Windows 7 SP1 version is released sometime in the first quarter of 2011 and you have installed it, you can run the Windows 7 SP1 cleanup tool to permanently remove the backed up files created during the installion of the Windows 7 SP1 to gain back around 1.5 GB of space on your system drive (Windows 7 drive).
For better performance, it is always recommend to have the virtual memory page file managed by the system and to not turn it off. By default, the page file is stored on your system drive (Windows 7 drive).
If your system drive is low on free space, then you could move the page file to be stored and managed on another internal hard disk instead to free the allocated space used by the page file on the system drive, or shrink the page file to reduce the amount of allocated space used.
When you create a system image while you are creating a user and system file backup, you can either let Windows manage the space used for backup history to have a maximum size of up to 30% of the total free space on the hard drive that you have the system image saved to used for system images, or have Windows keep only the latest system image and minimize space used by the backup.
Change Amount of Disk Space Usage by Temporary Internet Files
Temporary Internet Files is where Internet Explorer stores copies of webpages, images, and media of sites that you have visited in Internet Explorer for faster viewing later in Internet Explorer by not having to redownload them. By default, Temporary Internet Files is set to use 250MB of disk space. You can change this to be any amount (8 to 1024MB) of disk space that you want to be used for Temporary Internet Files instead if you like.
As you browse the web, IE9 stores information about Temporary Internet Files, Cookies, Websites Visited History, Download History, Form data, Passwords, and ActiveX Filtering and Tracking Protection data. For Firefox, click on “Clear Private Data” and delete “Cache” and “Cookies”.
If you have recently deleted a partition or shrunk a partition on the hard drive, then this will leave it as unallocated space until you either format it or extend it back into the partition to the left of it so that space is available for use again.
