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 programs to provide a quick preview. You can clean
up the thumbnails and caches of programs 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 his-
tory 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 references. By deleting or moving the files, these
entries become invalid.
Please note that files shown with an exclamation mark in TuneUp Disk Cleaner should only be used by expe-
rienced users.
