Which Files are Suggested for Deletion?
TuneUp Utilities searches for the following types of file which can normally be deleted from your hard disk with-
out causing problems.
Type Description
Temporary Windows files
Windows creates files to temporarily store data
that should normally be deleted after its tasks
are complete. These files can always be deleted.
Reports and logs from Win-
dows
Windows saves various reports and logs, e.g. for
error analysis or on the behavior of programs
and services.
Unnecessary Windows files
You can clean up the image preview for folders
and caches category to gain disk space.
Backup files of Windows
Repair programs like CHKDSK search your hard
disk for lost clusters and save them. These back-
ups are usually never used by users and can
therefore be deleted.
Windows history lists
Windows creates history lists, which may log
which files you were last working on, for exam-
ple. These are stored in the registry as ref-
erences. By deleting or moving the files, these
entries become invalid.
Temporary program files
Many programs create files to temporarily store
data that should normally be deleted by the pro-
gram after its tasks are complete. These files can
always be deleted.
Reports and logs from pro-
grams
Many programs write log files that can be used
to analyze their behavior. This can be helpful,
for example, when trying to solve problems.
Any log files that you do not plan on evaluating
can be deleted.
Unnecessary program files
Thumbnails of images are used by various pro-
grams to provide a quick preview. You can
clean up the thumbnails and caches of pro-
grams to gain disk space.
Backup files of programs
Many programs automatically create backups of
your files. These can be deleted if you do not
need them.
Program history lists
Many programs create history lists, which may
log which files you were last working on, for
example. These are stored in the registry as ref-
erences. By deleting or moving the files, these
entries become invalid.
