Clean up and Repair
Category Description
Zero-byte files These files contain no data.
Saved lost clusters Repair programs such as Chkdsk scan your drives for
lost clusters and save them. These backups are
rarely used.
Internet cache All pictures, texts and animations that you view in
Internet Explorer while surfing the Internet are saved
in the cache. If you visit a website again, the texts
and images can be loaded from the cache more
quickly than from the Internet. It is nevertheless
advisable to empty your cache from time to time.
Recycle Bin All files in the Recycle Bin can be safely deleted.
Log files Many programs write log files that can be used to
analyze their actions. This can be helpful for example
when trying to solve problems. Any log files that you
do not plan on analyzing can be deleted.
Backups Many files automatically create backups of your files.
These can be deleted if you do not need them.
Temporary files These are used by different programs to temporarily
store data and should normally be deleted by the
program when you are done working. These files can
be deleted in any case.
Temporary help
files
These files are used to display help files more
quickly.
It is important that you are careful when using DiskCleaner so
that necessary files are not deleted. The module finds a
number of files that are probably not needed, but the program
can never determine with certainty whether a file is needed or
not. A .sav file can be an unneeded backup copy of a text
document, or a computer game save. And a zero-byte file
could be a useless entry in the file table or part of the copy
protection for a program that won’t work when the file is
deleted.
Don’t take any risks!
How can you check which files the program deletes and
which ones it doesn’t?
First, check whether you can exclude individual categories.
To do this, simply clear the check box in front of the desired
category, for example Backups or Log files.
