What are junk files?
Junk files are files that you did not create on purpose, but that accumulate on
your computer as you use applications, and, particularly, as you browse the
Internet.
Applications often create temporary files as you work, either to store
intermediate versions of files that you are creating, or to keep track of status
changes. If the application exits unexpectedly, it cannot remove these files in
the usual way, although they are not used the next time you start the
application. The files stay on your disk and take up disk space.
If all temporary files were stored in the same folder with the document files,
you might be able to find them and delete them yourself, but these files are
often stored in the Windows temporary folder, or in application-specific
temporary folders.
Indicates this kind of file...
Compressed archive files
created by different
compression programs.
Internet files. They will be
opened by your default
browser.
Multimedia files. They can be
opened by a multimedia player.
Graphics files that are usually
opened by your Internet
browser.
TIP: To make sure that you have deleted all unusable temporary files,
schedule UnInstaller's QuickClean wizard to run regularly, as described
in "How do I schedule QuickClean to run at a specific time?," on page 15.
