I am a beginner.
It was suggested I download CCleaner. What is it all about?
Are there detailed instructions anywhere?
After I use CCleaner I go into Analyze and it says.
Details of files to be deleted. No files deleted yet.
I click run cleaner. A window says these files will be permanently be deleted. I click ok.
It says cleaning complete. O bytes removed.
I click analyze it says O bytes to be removed. I come out of CCleaner.
I go back into CCleaner Analyze, it says 279 bytes to be removed. Details to be deleted (No filed have been deleted yet).
What is it all about?
Where should I look to find what has been deleted.

Have a read here Zaffy,
