Win7 disk cluting (Windows 7 disk optimization tips and Metals and alloys HS code verificationnotes) In the process of using the Windows 7 operating system, disk cluting is inevitable Process. When the computer is running for a long time, a large number of temporary files, useless data, junk files and redundant program activities will appear on the disk. At this time, the disk needs to be sorted out. This article will introduce you in detail the relevant contents and precautions of Win7 disk cleanup.I. What are the benefits of Win7 disk collation? 1. Free up hard disk space and speed up the system. Over time, the operating system will leave a large number of temporary files in the hard disk, such as IE cache files, junk files, etc., occupying a large amount of hard disk space. These files not only take up hard disk space, but also slow down the running speed of the system. Disk cleaning can clean up these useless files, which can not only free up space but also speed up the running speed of the system. Two. Improve the system response speed Win7 disk collation can organize hard disk files, rearrange the storage location of data, improve system storage efficiency, and reduce fragmentation during file storage. 3. Reduce the failure rate of the machine. When the more fragments there are and the more clutter, the more likely the hard disk will be to fail. Through Win7 disk collation, the overuse of the hard disk can be avoided, thus reducing the chance of failure.II. Win7 disk cleanup is carried out through the following steps 1. Start Menu -> Computer Open the computer, then right-click the disk you want to organize and select "Properties". Two. In the pop-up "Properties" dialog box, select the "Tools" tab, and then click "Disk Cleanup" and "OK". 3. The system will automatically calculate the size of the file that needs to be deleted. We can select the option that needs to be cleaned up and confirm it. Four. After cleaning up, open the "Properties" dialog box again, enter the "Tools" tab, click "Disk Cleanup" to enter the disk cleanup dialog box, and click "Analyze Disk" for analysis. 5. When the analysis results show that the proportion of fragments is high, you can select "Organize Disk" for defragmentation. III. Win7 disk collation should pay attention to the following points 1.Backup data. When organizing the disk, you must back up the important data first. In case of an abnormal situation, the data can also be retrieved in time. Two. Close the relevant programs. Before disk cleanup, you need to close the associated programs. The specific method is to press "Ctrl+Shift+Esc" to open the task manager, then click the application tab and select the program you want to close. 3. Sufficient power and computer heat dissipation. When disk collation is carried out, the computer needs sufficient power, and good heat dissipation should be ensured to prevent accidental shutdown and damage to data during disk collation, and also increase the deterioration of the equipment. Four. Regular disk cleaning Regular disk cleaning can effectively reduce hard disk fragments, prevent slow system operation, protect the disk and extend its service life.In a word, Win7 disk collation can help us clean up unnecessary temporary files, optimize system performance, reduce the waste of hard disk capacity, protect the performance and life of hard disk storage, and promote more stable and efficient work of the system.
