I can think of no reason why Chrome does a lot of things it does.

You don't say if you were defragging the whole disc or just the files when using Defraggler, or what other settings you were using; you also don't say if it was one of your SSDs or HDDs. ('Optimise' is a term more often used with SSDs, defraggler can do that as well - But it does sometimes have problems recognising which is which type of drive). Not to worry, if you've found a defragmenter that you prefer then keep using it and get rid of Defraggler. As I said above: TBH I'm coming to the opinion that defragmenting (like Registry Cleaning) is something that may have been useful in the past with older OS's but is much less important now unless you are trying to cure a particular issue such as the gaming lag that you are trying to eliminate.

"... \Code Cache\js" is where Chrome stores Javascript files that it has gathered from webpages and compiled. This is done so that when Chrome encounters the same javascript again it doesn't need to compile it again but can use the already compiled one from "Code Cache\js", saving a little bit of time loading pages. If you delete that cache then all it means is that Chrome will have to recompile a java script if/when it comes across it again, (which is why the js cache fills up again). Most users wouldn't notice the time saved anyway, unless they have a very slow CPU or slow internet connection to start with. As to why CCleaner doesn't clear it by default who can say? It may be a deliberate choice not to or it may be an oversight. As Hazelnut said, if you want to clear it when you run CCleaner then just use Custom Clean and make the "Code Cache\js" directory an 'Include'. (You have to use Custom Clean to do that, Easy Clean/Health Check uses its own cleaning rules)

Defragmenting will always be contentious, because different defragmenters work in different ways. Some will 'compact/consolidate' (not compress) files on the disc, to put the free space all in one block. (But you have to Fragment files to do that). Others will defragment the files themselves, but leave them spread on the disc with freespace between. (It's faster to do that). So it's a choice between having all the free space together with some files fragmented, or having each file in one piece with the free space fragmented. You can't have both. Defraggler itself can do either, depending on what you are trying to achieve. Now that discs have got to 1TB and larger defragging the whole disc, ie. 'compacting/consolidating', can take time to do, and it's debatable whether it's worth it anyway. Firstly- With drives of 1TB or larger that's not as much of a problem as it was in the past with smaller drives. Secondly- It doesn't really save space. It just moves all the free space together. (Fragmenting files as it does it) Users of large drives usually content themselves with defragmenting the files only and letting them have space between. In the end it's your choice of what you want to achieve, and which defragmentation utility you prefer using to achieve it. Here's a post about the diffrence between defragging files and comapcting files: https://forum.piriform.com/topic/52009-defrag-with-many-holes-normal/?tab=comments#comment-296519 Here's one about Defraggler working in two of the different way that it can do: https://forum.piriform.com/topic/56605-defrag/?tab=comments#comment-314363 Here's one about using a different defragmenter after already using Defraggler: https://forum.piriform.com/topic/55852-defraggler-time-taken-to-defrag/?tab=comments#comment-311733

For what it's worth the CCleaner documentation can be found here: https://www.ccleaner.com/docs/ccleaner However it's somewhat out of date and doesn't reflect the many changes to CCleaner that have been made over the last few years. We have been promised that they are working on updating all of the Piriform documentation, but I don't think that anyone is holding their breath waiting for it to happen.

CCleaner can uninstall itself in Windows, just use Tools>uninstall and select CCleaner itself. However I'm not sure about CCleaner for Mac, it doesn't have the (same) tools.

I don't know of a way to set CCleaner to do that. Personally I would use the built-in Windows Command Prompt to find any files with a (2) in the name, and work from there. If there is a file with a (2) then there is probably one without it. Open a Command Prompt window and then type the following lines: cd\ dir /b /s *(2).* It will take a few minutes to find all the files. Explanation: cd\ takes you to your root directory, usually C:\ dir searches for files and folders, I've specified two options there: /b tells it to just list the path/filename with no other information, /s tells it to look in all sub-directories. *(2).* tells it to look for any filename (and folder name) that contains (2) at the end of the filename. You can refine that to search just for the filetypes you want. If I'd just wanted to search for text files I could have used *(2).txt Typical output will look like this: If there are a lot found then you could direct the output to a text file for ease of reading, I'll leave how to do that for you to look up. Once you have that list of everything ending with (2) you can look for any corresponding file without the (2), it's most likely in the same directory but you could use dir again to check. eg. from the list above I could: dir /b /s vote?lizard.txt to find the pathname, if it exists. Note the '?' you need to put that in filenames instead of a space when using the Command Prompt. The Command Prompt is a tool that is often forgotten about these days, but is pretty useful/powerful for stuff like this. For example here are all the options you can use with a simple command like dir: https://www.howtogeek.com/363639/how-to-use-the-dir-command-in-windows/

Are you looking for recommendations?

Pictures tell a thousand words. This will always wipe MFT Free space: This should only wipe MFT Free space if the option to do so has been ticked in Options>Settings

Can you see what section it is getting stuck on? If you are using Easy Clean/Health Check then the section it's stuck on should be show underneath '# Trackers' and/or '#MB of Junk'. If you are using Custom Clean it should be shown at the top of the results window.

It's a badly worded message that they have promised to change. It doesn't actually mean that you are offline, it means that Health Check cannot contact CCleaners server for some reason. Those 2 functions need to contact the server to check against the database for any updates available to applications on your computer. (Note those 2 functions are only available in the Pro version). It may just be a connection problem in which case try again later, but more often it is your Anti-Virus blocking CCleaner from passing through the Firewall to contact the server. Try making CCleaner an exception in your Anti-virus, - google for how to add an exception in the particular AV that you use. (eg. google- "Add an exception to Avast anti virus" would find instructions for Avast).

The error message show in the original post from last July is what is displayed when files cannot be deleted by CCleaner. This is usually because of one or more of the following: the files are protected from deletion, (System Files, self-protected files for your AntiVirus, user protected files), the current user does not have permission to delete/modify those files, the files are open and are in use. PS. You should not try to remove duplicate System Files, often the system needs the same file in more than one location (particularly .dll's) and removing duplicate System Files may/will cause your computer to act strangely, or even stop working at all. Duplicate finder should only be used to find dupicates your own files; documents, photos, videos, etc. (The option to find duplicate System Files is there for advanced use by a computer technician).

I don't know, Flash is supposed to be phased out this year (or maybe not we've seen that before) which may be why Edge Chrome is deleting it. Or it may be just a setting in the new Edge that you have to change? Whilst I have downloaded the new Edge to stay up to date I don't use it - I use Firefox 99.9% of the time.

Of course remember that Edge Chrome is now officially released this week, and so everthing 'Edge' is going to change again.

I'm not sure that is a bug; "nazwisko, imię" translates to 'Surname'. So which to use would would depend if Kazim had used 'Kazim' or 'Wąsowicz' or even 'Kazim Wąsowicz' when purchasing his licence. To register he would have to use the same as when he purchased. His last reply indicates that it was his missunderstanding and "not serious".

Can you see what section it is getting stuck on? If you are using easy clean the section it's stuck on should be show underneath '# Trackers' and/or '#MB of Junk'. If you are using Custom Clean is should be shown at the top of the results window.

Defragmenting a disc and defragmenting files are (slightly) different things. Defraggler will do either, but doing both is a bit counter productive. Defragmenting a mechanical disk will try to fill up the disc clusters to get all files together in 'filled up' clusters. That means that to fill up empty space in those clusters some files have to be split (fragmented) - so much to fill a cluster and the rest in another cluster. Defragmenting files will keep the files together without splitting them up, but that means that not all clusters will be full to the top. It's a case of choosing which you want to do. If you are short of disc space then defrag the mechanical disc to free up disc space. If you want files to open slightly faster (you won't even notice) then defrag the files. With the larger drives fitted as standard these days defragging has become much less important that it used to be with small capacity drives.

The name has been changed - it's now called Smart Cleaning. The documentation needs updating but it's a big job because it's been neglected for a number of years.

Indeed they can, but can also save bits that they want to. Which is why programes like CCleaner still exist. With a bit of knowledge you can clear more than they do themselves, as long as you are careful of course.

I'm in the pub at the moment but when I get home I'll PM you my batch file for Cleaning Firefox caches, cookies, and supercookies.

TBH if it's Windows 10 then the built in Storage Sense is probably all they need.

Another one outdated in the documentation: /AUTO is now /AUTOS (A combination of Auto+Silent?). We had a thread about that last week where a user couldn't understand why his /AUTO kept changing to /AUTOS in Windows startup. It's a technicallity, but /AUTOS is what CCleaner now sets in the registry (and thus Windows startup) if you have 'Run CCleaner when the computer starts' selected. If you use /AUTO in a batch file it should still work, but it's usually better to use the latest version of a command switch. In your parents case then 'Run CCleaner when the computer starts' may be the simplest solution, it will then do a clean in the background everytime they do occasionally turn on the computer. They won't even know it's doing it. You can find that switch in Options>Settings.

I believe that this is another of the 'private/secure' browsers that does not save your cookies, history, cache, etc., etc. to disk. The question has to be that if the browser is not saving these things to your disk then is there even anything for CCleaner to clean?

A lot of the documentation is out of date, they are supposed to be working on updating it. I believe that Smart Cleaning (previously Monitoring) in the Free version now works like this: There are two parts to the smart cleaning settings in CCleaner Free: When you tick 'Enable Smart Cleaning' it automatically ticks 'Tell me when there are junk files to clean' as well. This then checks every so many (8?) hours to see if there is more than 0.5 GB (although that may now be 1 GB) of junk to clean, and if/when there is it gives you a pop-up warning and asks if you want to clean it. If you don't reach that much junk then you won't get a notification. If you say NO to the pop-up then it will wait for another so many hours before poping-up again. If you untick 'Tell me when there are junk files to clean' then when it reaches the GB limit it will clean automatically without giving you a pop-up. The Pro version allows you to change that GB limit with 'If cleaning saves more than', as well as letting you set verious options for automatically cleaning your browser on closing.

CCleaner will not let you wipe the entire drive for drive C, for a very good reason. Drive C is where the Windows operating system is installed. If you wipe it entirely then you have no Windows and your machine is as much use as a brick. (It's called 'bricking your machine').
