How to free the Hard Drive space being used after upgrading to the Windows 7
There are several factors that can affect the hard disc drive (HDD) space being used:
- The operating system has a Temp file (directory) that will retain 3 GB or more to store temporary files. The Temp file will reflect a HDD size equal to the temporary file content that is allocated to the file. Because temporary files are, as the name would suggest, intended to be temporary in nature, the files that reside in the Temp directory can be deleted without the risk of data loss.
- When using the OEM version of Windows 7 Upgrade Kit obtained from your Computer's manufacturer to upgrade the Windows Vista Operating System, a win7upgrade folder may be created on the hard drive in order to perform the upgrade. Once the operating system upgrade is complete, the win7upgrade folder is no longer needed and can be deleted without the risk of data loss. Doing so will free up to 2GB of HDD space.
- Often during the upgrade process, a Windows.old file will be created on the hard drive as a location to save user data files that were present on the computer before the upgrade. The Windows.old can be very large. Review the contents of the file and delete all or part of that file if desired.
IMPORTANT: Because the Windows.old file contains older user data files, to avoid any unintended data loss, you should review the content of the file very closely before deleting anything.
- By default, the Operating System reserves 15% of the hard disc drive (HDD) space for the System Restore feature.
IMPORTANT: Because the System Restore feature can return your computer system files and programs to a time when everything was working fine, it is a very valuable asset to help safeguard your e-mail, pictures, documents, and other personal files. Reducing the amount of HDD space reserved for the System Restore feature or deleting System Restore points can negatively affect or eliminate the usefulness of the System Restore feature.
