Even when I do NOT start CCleaner v6.21 (on 64bit Win10) I can see that CCleaner writes something once a day to the file "BugReport.log" in subfolder LOG. Why? Is there a background service? I can't see it. How can I forever stop this background service and writing to all *.log files?

When I go to official download page: https://www.ccleaner.com/ccleaner/builds Then under CCleaner Portable still only v5.9.1 is listed. When will v6.* Portable be available for download?

Behind some of the entries in "Custom clean" section there is a "*" What does that mean?

I ticked in "Windows Explorer section of CCleaner v5.92 the checkbox "Taskbar JumpLists" and run it on 64bit Windows 10 v21H2. Much to my surprise all the corresponding file entries in the two folders: C:\Users\thomas\AppData\Roaming\Microsoft\Windows\Recent\CustomDestinations\ and C:\Users\thomas\AppData\Roaming\Microsoft\Windows\Recent\AutomaticDestinations\ are NOT cleaned but be kept after a CCLeaner run. Whats wrong? How can I get rid of them otherwise? Do I really have to add them manually in the "include folder" section?

Hmm, yes I am running Defraggler from USB flash drive. Why is Boot time defrag not possible?

Good idea, but wrong. I marked partition C: (with pagefile.sys and swapfile.sys on it) and......menu "Boot Time Defrag" is still disabled. Maybe it plays a role that partition C: is on a SSD and partition D: on a hard disk? Moreover it should be possible to boot time defrag partitions with NO pagefile.sys on them. Think about (at runtime) unmovable MFT tables, or Registry Hive files, or System Volume Information folder (for System Restore Points) or RECYCLE BIN folders or ...... They need to be defragmented at boot time What other reason could it be for greyed out menu? Does Defraggler Boot Time Function depend on a (which?) Background Service? How does Defraggler setup a Boot Time Defrag? Maybe it has insufficient access (write) permissions to Task Scheduler or Registry or startup folder? In this case Defraggler should show a corresponding warning

I log in as a user which is member of the Administrators group. Have a look at the attached snapshot

Here (Win10) this menu ("Boot time Defrag") is DISABLED (=greyed out). Why?

@nukecad: Thank you for your explanation. Just one more question: You talked about "unmovable" files. Yes, I know. These are MFT tables and registry files (beside pagefile). To defragment these some defragmenters offer "Boot time" defragmentation at next reboot which does the job when there is no file lock on these critical sectors/files. Does Defraggler have such an Option? I cannot find it. Maybe users can easily setup such a job by using Task Scheduler? Do you have *.reg Script which injects a corresponding One-Time Task into Registy? Thank you

I want to shift all files to the beginning of the disk partition. With normal defrag or optimize only defragmentation took place. But there are still huge space/sector gaps between files after defrag+optimize. How can I tell Defraggler tool to shift all files without gaps to the partition beginning?

In my notebook I have 2 partitions: C: and D: C: is located on a SSD and D: on a hard disk Now I mark partition D: on partition pane at the top and click "Analyze". Afterwards I click on button right of it and "Defrag" menu. Much to my surprise a warning pops up: "Volume D: appears to be solid state. Defragmentation may reduce its lifetime. Are you sure to proceed?" Why does Defraggler think that D: is on the SSD? Or does Defraggler show only D: but mean C: (and want to defrag it)? This is clearly a bug. Pls fix this. Thomas

When I go to Tools-->Drive Wiper Then I can start to erase free space. Until here everything is clear. But when I go to Options--->Settings then there are some confusing settings: 1.) At the bottom users can select on which partition to wipe free space. Why do I have to select partition here AGAIN? I though I have to select it on Tools-->Drive Wiper? 2.) Just above there is a check box "Wipe cluster Tips"? Cluster Tips are only the remaining unused parts of partially filled clusters. But it does not mean FULL free clusters. So are always only clusters tips wiped but not the actual all free space on a partition? These options are at least misleading.

I am new to Winapp2 and tried to use it for CCLeaner. I downloaded newest winapp2ool.exe from github and put it into CCLeaner installation directory (with winapp2.ini). Then I started winapp2.ini and selected 2.Trim--->1. Run (default) to trim all unfound applications on my system from winapp2.ini file. Afterwards I started CCleaner v5.78 and inspected in Custom Clean--->Applications all remaining entries with stars Surprisingly a lot of them still appears: E.g. for Opera and Brave browser. I never installed them. So why are they NOT trimmed/removed from winapp2.ini (...and CCleaner)?

When I go to Custom Clean then for some browsers the deletable items are listed. Is the deletion for portable browser installations suitable as well?

When I go to Custom Clean then users can find a lot of options in each section. How can I enable ALL options of such a section (e.g. Google Chrome) with ONE Click? Do I really have to tick every checkbox manually step by step?

I section "Custom Clean"--->Applications after a lot of entries a star * appear. What does that mean?

Currently I am running portable version of CCleaner v5.44 but want to migrate/update to portable Version v5.77. Very important is that I can keep all my approx 60-70 specified INLCUDE directories and KEEP cookies settings Can I simply copy "ccleaner.ini" from old CCleaner installation folder to new CCleaner installation folder? Will new CCleaner v5.77 successfully recognize all these old, previous settings?

CCleaner offers to clean cookies. Can CCleaner clean cookies from portable versions of browsers as well? From where does CCLeaner know where to find portable browser installations? I need in Cookie panel a new column showing the location of the cookie

Ok, you are explaining why CCleaner is CURRENTLY so slow. But that doesn't mean that CCleaner will be slow forever. Other washer/eraser tools show that the task could perform MUCH faster. Maybe CCleaner should implement: - direct MFT/Cluster/NTFS access instead of using windows file opening DLLs - use concurrent, bundled threads - other possible tricks like grouping of cluster wiping So there is much room for CCleaner improvements. Could you put this on your feature request/todo list? I prefer to use only ONE tool instead of multiple. Since CCleaner is good for many other tasks I am willing to elect it as my one-and-only utiltity. But erasing performance is really a problem. Thank you Thomas

Due to my observations I performed the following experiment (on 64bit Win7 with 16GB memory): I have a huge dir tree with approx 100000 files between 10kb and 1MB each with a total size of approx 20GB I added/included this dir tree as additional folder to wipe. When I perform a CCleaner run it takes around 7 hours (!) to clean all these files (remaining clean stuff is negligible) Before cleaning it with CCleaner I made a copy of it. As comparison benchmark I performed a wiping of this duplicate dirtree with other tools like WipeFile. Surprisingly the WipeFIle requires only ~30 minutes for the same task. That means CCleaner is significantly slower than other tools. - CCLeaner uses "Secure file deletion Simple Overwrite (1 pass) - WipeFile uses Random overwrite (1 time) This is disappointing I suggest urgently to improve wipe speed in the next CCleaner release. Thank you Thomas

In former times I could download a portable version of CCleaner. I do not find this download any more. Is it abolished? Thomas

On my Win7 system I have two independent Firefox installations: - The first "normal" installation of v58.0.2 - The second, portable Firefox v52.60 Firefox ESR version In CCleaner I defined a couple of Cookies which should be kept. When I run now CCleaner it detects and cleans successfully the cookies of the first Firefox installation since it knows the profile path from registry. Unfortunately CCleaner does NOT recognize and clean the second Firefox installation. Is there a way to let CCleaner clean the second Firefox installation (especially the cookies which are not in the "keep"list) as well? Thomas

ok, thank you. When I read the linked guide it does not become clear what I should specify as path. Assume I have Firefox ESR then I could specify: D:\FirefoxESR\Data or D:\FirefoxESR\Data\profile A subfolder D:\FirefoxESR\Data\profile\sam as mentioned as example in the guide does NOT exist. So what should I write in ccleaner.ini?

As far as I can see CCLeaner looks into Registry to find browser installations on the current system and apply afterwards e.g. cookie washer. It works. BUT what if I setup PORTABLE browser installation (like Firefox ESR or Portable Chrome)? Since these browser installations do not use Registry CCleaner cannot find them. How can I tell CCleaner to apply Cookie washing rules onto these portable browser installations as well? I can imagine that there is an option to enter base pathes of those portable browser installation but cannot find them. Thomas

When will this option be implemented?
