First of all, it is recommended to use 3 6 0 security guards or Q Q computer housekeeper to clean up the garbage! ! !
Open the main interface of 3 6 0 Security Guard, click the yellow broom of "computer cleaning" at the top, click the "garbage cleaning" option at the bottom, click "Start scanning" on the right, and click "Clean up now" after scanning.
Open the Q Q computer manager interface, click the "clean up garbage" option above, check "clean up garbage", then click "start scanning" and finally click "clean up now".
There are several factors that will lead to the phenomenon you mentioned, and the solutions are as follows:
1. Some junk files in the recycle bin have not been deleted. Go straight to the recycle bin and delete them completely.
2. There are some hidden files in your partition, such as hiberfil.sys file (dormant), pagefile.sys file, or backup files made by some recovery software in each partition. These are some important system hidden files (the system can't see these files by default), so don't delete them easily, lest the system can't run normally. However, these files can be transferred to other partitions through the system settings of Windows, and the space of drive C can also be increased. (Note: You can't directly switch to other partitions, and you must change them through the system settings of Windows. )
3. A player with video or audio installed will generate a large number of hidden caches in order to improve the smoothness of playing video. This can be deleted without adversely affecting the system. Specific deletion method: You can use 3 6 0 security guards or Q Q computer manager to open the garbage cleaning option, and check the player cache option you want to delete to delete and restore the space in your partition.
4. You have installed a lot of games, and many online games will produce a lot of caches in order to speed up your game. Please also use 3 6 0 Security or Q Q Computer Manager to clean this up. Also, you often save a lot of progress after playing games, which will also increase the space occupation. Please enter related games and delete unnecessary progress saving. Can also release a certain amount of space.
5. You made a system backup such as one-click Ghost or one-click recovery backup, and the backup files were saved in the partition in the form of hidden and protected files (the system can't see these files by default). These files cannot be deleted to avoid losing backup files or images. If this kind of file takes up space, you should change the default storage space of backup through one-click Ghost software instead of cutting and transferring files directly to avoid Ghost failure.
6. There may be some disk errors in your partition, which will lead to capacity reading errors. Run disk checker to check the repair, and you can solve it.
7. Open "My Computer", open drive C, there is a Windows folder, open it, find a "Temp folder", and delete all files in it (other applications need to be closed in advance). There is a temporary internet folder next to the temp folder. Open it and delete all its contents. Be sure to delete the Temporary Folder and the Temporary Internet Folder, but delete all the contents in the folders. Remember! ! ! It is best to do it once a month. ?
8. Double-click this computer or my computer on the computer desktop. Point to each partition C, D, E, F, right-click Properties-General Tab-Disk Cleanup, and then switch to Tools-Check-Scan Drives. ?
9. Double-click "This Computer" or "Computer" or "My Computer" on the computer desktop. Point to each partition C, D, E and F in turn, right-click Properties, then switch to Tools-Optimization-Optimization, and then optimize each partition C, D, E and F in turn. If you haven't run this program before, and your hard disk is large, it may take more than 1 hour (if you think it takes a long time, you can stop and run it several times later). This program should run once every month/kloc-0, and the running time will be much shorter after the second time. ?
Attachment: How to view and display hidden files: Open my computer, click Tools-Folder option in the menu bar, click View in a new window, remove the check box in front of hidden protected operating system files (recommended), and click Yes in the pop-up window; Select Show All Files and Folders in the Hide Files and Folders option, and then select OK.
