I use CCleaner Free v5.60.7307 (64-bit) on my WIN10 Home x64 desktop. Over the years I have been storing the cc_yyyymmdd_######.reg files on my HDD; about 45 now exist. Is there any practical reason for me to retain these files? Should I retain all 45 files? I just mistakenly ran a cc_.reg file that was created on Jan 13, 2019, thinking that its contents would open in NOTEPAD/text editor; I wanted to view the contents, only. To correct this, should I run the most recent cc_.reg file to overwrite the Jan 13th edition? TNX for reading this.
