Cleaning up the garbage in your computer seems simple. But sometimes the useful or valuable files that were found after use were “unexplained” and disappeared. Is it because the ability to trust software still ignores the things that need attention, and what should be paid attention to when cleaning systems and software? Below, the system home Xiaobian tells you three major elements to clean up the garbage. 1, comprehensive cleanup without leaving a dead corner The current system maintenance software claims to be able to clean up your computer in a stable and comprehensive manner, but in fact there is no software that can do without leaving any dead ends. To know the answer to this question, you need to first understand the causes of system waste. Generally speaking, it is decided by three aspects: the system itself, application software, and user usage habits. For the system (such as a version of Windows), because Microsoft has released a system that everyone can conduct in-depth research, so which locations are prone to garbage and what kind of garbage is produced, there are traces. In addition, developers of system maintenance tools from various vendors learn from each other, and it is not a big problem to clean up. However, for application software, due to its large number and complex content, and the inconsistency of development standards, the generated junk files are difficult to be archived in a fixed directory, so that no garbage can be generated for all application software. Ground cleaning is impossible. For the garbage generated by users, the garbage system maintenance software is even more difficult to judge. If a user often reads novels, movies, or other documents at once, and the user does not have good file storage habits, and the files are stored everywhere, then what can the garbage cleaning tool say about the novel and the video is garbage? If you want to clean the system without leaving a dead angle, 360, CCleaner, system optimization masters, etc. can all do this. For the garbage cleaning of the application software, in addition to the cleaning of the above tools, the application software that the maintenance tool fails to clean up needs to be manually processed, generally entering the advanced setting window of the application software to view the cache or temporary files. Where is the directory, delete the files after entering. For the user's own junk files, this is the most incapable of the system maintenance software. It is up to the user to develop good file management habits. It is best to store all kinds of files in the classified fixed directory. After use, Manually delete those unneeded files to free up space on your hard drive. Tip: The dead corner garbage in the system varies from person to person depending on the user, so there is no fixed tool for cleaning up. However, each type of garbage must have a fixed storage address or file type, so there is a method that can be used universally, that is, to customize the dead corner garbage cleaning batch, including the directories and files to be cleaned up. The specific method is to use the system internal commands DEL and RD and combine its parameters /F, /S, /Q to construct a specific batch program, the format is: DEL /F /S /Q < a certain type of file in a directory >RD /F /Q <A folder> is the content of a garbage cleanup batch file as shown. The parameter /F indicates that the read-only file is forcibly deleted, /S indicates that the files in the sub-directories of each level are deleted, and /Q indicates that the silent deletion does not confirm the prompt. 2, automatic cleaning Careful selection due to the diversity of garbage data, the user's own judgment is not only very difficult, even if the user has a technical basis, it will take time and effort to find and deal with it. Therefore, under normal circumstances, we generally choose system maintenance software that can automatically scan and classify garbage, and the software automatically cleans up the garbage for us. For the automatic cleaning function provided by the system maintenance software, be sure to check the automatic cleaning settings before opening. If there are items that need to be retained (for example, “use traces”, some users are very concerned about it), then To remove the check box. Otherwise, when you understand yourself, things can't be found. Although some automatic cleaning tools will remind us that there may be important information that has been deleted by mistake, we can't think that everything can be done. In fact, the use of automatic cleanup may still hide a risk, which is mainly reflected in the accidental deletion of useful data for users. This is the question we will discuss next. 3, custom cleaning to prevent accidental deletion is not to say that the system maintenance software scans out "garbage" data can be safely cleaned, because the user's habits are different, some are considered by the software to be "garbage" data, in some The user is a useful file there. For example, the cleanup tool generally thinks that the files in the TEMP or TMP folder are temporary files, which can be treated as junk files, and some users who engage in programs, or users who like me to drum up the computer, may use some experiments. The program or data is placed in the TEMP folder that you created. But this does not mean that the things in this folder are useless. If you simply listen to the self-made claims of the system maintenance software, you may lose your own experimental data. So, how can we achieve the two conveniences of cleaning up garbage and retaining useful data? This requires a custom cleanup instead of a full automatic one-click cleanup. Taking the garbage cleaning module cleaning system of the driver wizard as an example, the software detects that the QQ software generates 69.9MB junk files, and these files will be cleared according to the automatic scheme. However, in the 69.9MB so-called "junk file", it contains the dynamic expression pictures received during the QQ chat process, and some useful pictures sent by the netizens. If the user has the habit of looking back at the chat history, then the full cleanup will make all of these history records disappear, so for the user, the useful image information is mistakenly cleaned up as garbage, then you need to set it in advance. Reserved. Software downloaded by software management tools such as 360 software housekeepers is often an object that is easily deleted by mistake. These softwares are useless for some users, and for some users who collect software versions, they want the software in these directories to be permanently stored. However, garbage-cleaning tools such as computer housekeepers will often find these software as their own “credits”, which are included in the cleanable default options. At this time, if you choose the default one-click cleaning option of the software, then all the software that you have worked so hard will disappear without a finger. In this case, you also need to set the reservation in advance. Tip: In order to prevent accidental deletion, you need to customize the cleanup to exclude information that you think is useful. Click the <quo;Junk Details” text link to go to the Cleanup List window. For the items you wish to exclude, click the “Ignore” button at the back to clear the cleanup of the project.
