File Analysis
TuneUp DiskCleaner now shows the results of the search. The right side of the window contains a table that indicates the number of files found in each category, such as 0-byte files. The number in the Space used column indicates how much space can be recovered by deleting all files in this category.
Additional information on the selected category is shown on the left.
TuneUp DiskCleaner searches for all types of unneeded data, which can normally be deleted from your computer without causing problems.
Types of Unneeded Files
- 0-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 deleted.
- Log files: Many files 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.
Don't take any risks!
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 0-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.
How can you check which files the program deletes and which ones it doesn't?
Exclude categories
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.
Backup categories with RescueCenter
You also have a second option. Click a category with your mouse. Details on the selected category are then shown on the left side of the screen. Here, you can select Backup with RescueCenter to be 100% safe. All deleted files are backed up automatically by TuneUp RescueCenter in compressed form so that you can restore them if need be.
Viewing all files that have been found for deletion individually
When you click Show Details in the information area, TuneUp DiskCleaner opens a new window that contains information on all of the files in the selected category.
You can clear the check box in front of any file by clicking it, thereby excluding it from deletion. You can also click Open file to view the contents of the file to see if you can delete it safely.
