I am performing analysis scans only, one immediately after the other, and on the exact same system in the exact same state (click on any of the images to enlarge):ĬCleaner identified 562MB worth of junk files for deletion. CCleaner vs Wise Disk Cleanerįirst off, a comparison between CCleaner and Wise Disk Cleaner’s junk file cleaning abilities. I am now going to revisit that topic and show you just how CCleaner compares when performing its core functionality. ![]() Way back in 2012 I wrote a series of articles comparing CCleaner’s effectiveness with a number of free alternatives and, in every case, CCleaner came out second best. I’ve been messing with computers for over 40 years, have been fixing and building computers for 25 plus years, and started writing about computers, technology, and software, in particular, some 15 years ago. Seems every time I write anything negative about the popular junk file cleaner, there are plenty of users prepared to jump to its defense. ![]() A sysadmin who removes files owned by me is going to hear about it.īTW, debian dpkg does not remove configuration files by default (it has an option for that) and that only covers system configuration, not users.CCleaner certainly has a faithful following. In other words, the user may not be aware the sysadmin decided to remove the package and might object to its removal.Īt the end of the day, the only clear rule that works is: what is owned by the user is his and shall not be removed by third parties, no matter how well intentioned. If that has never happened to you, you probably have never worked in a small high-tech company (in large corporations, to rebel is usually pointless). Then there is the case of the nazi sysadmin (I met some) who decides that a specific application is useless crap and removes it some users rebel and demand a reinstall. I would want a package removal process to fall on the safe side and not remove them. If these are not small, then they do contain some valuable data. But these are usually small: not removing is no issue. Of course, configuration parameters specific to the application are good candidate for automatic removal. On the other side, removing these files erases a long email history that could not be reconstructed. You can argue that the format of the data being specific to the application, there is no point in keeping the files if the application is removed. ![]() The problem I see is with the use of the word "clearly".įor example, some email readers organize the emails in a specific way (directory tree, database, etc.). This data is important to the users, since it records their past operation events, which events have occurred (and these records may have legal significance) no matter if our software is removed or not. We take _great_ pain of organizing our software so that we _do not_ remove any user data if our software is removed or upgraded. Professionally, I work on train control systems that create historical records. When you remove the software, the folder is gone, and so is your labor of love. At least each user decides for himself if and when to delete things.Ī note about the source of my bias: I have been hit a few times on Windows by applications, like drawing or document tools, that by default store the user's file into their own folder, something like c:\Program Files\XYZeditor\Documents. What to do with other users data? Should the package manager start scanning all user's home directories and cleanup files under them? Is it wise to let the administrator or a simple user decide when it is appropriate to delete others users' files?Īll considered, a cleaner application sounds not so bad. The package is removed by root, or one specific user if capabilities are used. How happy would you be to see files disappear suddenly under you? What rights has the package manager to remove that data? This may happen while a user is logged on. As the "personal" indicates, it includes user's own data. ![]() Why: user's data is user's personal property. I may have a biased view above package removal, but I do not see why and how removing a package should remove user's data.
