Why does disk space come into the computer health
section? Every operating system and application
needs free disk space to operate, without this
disk space your operating system will grind to
a halt.
Windows itself need space for temporary files,
including space for the memory swap file to grow.
This file allows you to operate more applications
seamlessly as it swaps data from the hard disk
swap file to it's memory.
Such things like Internet Explorer will create
lots of temporary files which makes up the web
pages you view in the browser. Installing software,
will create temporary create files as part of
the install process.
When you edit documents, the word processor will
store histories of changes you've made.
There are many things which will use disk space,
most of the time the space is reclaimed. Occasionally
the files are left to waste space. Having plenty
of disk space to accommodate this ongoing requirement
is important to maintain a stable operating system.
There is a utility built into most versions of
Windows which handles some of this, called Disk
Cleanup.
