2. If your computer is full because the capacity allocated to disk C when installing the system is too small, you can use the disk management tool that comes with the system to solve it. The operation steps are as follows:
3. Click this PC- Management-Storage-Disk Management.
4. Right-click the disk to be compressed, select the compressed volume, enter the corresponding capacity, and an unallocated partition will appear. Right-click drive C again, select extended volume, and enter the capacity of this unallocated partition, so that the capacity of drive C can be increased without formatting.
This method is very convenient, but it should be noted that if your C disk and D disk are not the same disk, you can't increase the capacity of C disk. For example, the author's drive C is a solid-state hard disk of 120GB, and drive D is a mechanical hard disk of 1TB, so the maximum capacity of drive C is only 120GB, so it is impossible to borrow the space of drive D to increase the disk.
6.cclean frees up disk space.
7, unable to expand the capacity of C disk, you can consider slimming disk. Windows system will produce a large number of cache files in use, and after cleaning, it will release a few grams to dozens of grams of space. Some friends will use some security guards' cclean files after the C disk is full. However, due to the current technical problems of security guards, there is a certain risk of system collapse, so it is best to clean it manually.
8. Click "Accessories" of "Program" in the start menu, click "System Tools" and then click "Clean Disk", select drive C, confirm, select all ports, and then confirm;
9. Click "Disk Defragmenter" in "System Tools", and it will take a long time to wait patiently. (Note: SSD does not need to be defragmented. ) 3 After repeated installation and uninstallation, the system keeps many useless DLL files, which should be deleted; Click the Start menu, click Run, and type "regedit" in the text box; 5. Open the registry editor window and open HKEY _ Local _ Machine \ Software \ Microsoft \ Windows \ Current Version \ Shared DLLS branch in turn. On the right side of the dialog box, there is a number in parentheses after its key data. If the number is 0, it means that this DLL file has become garbage, so delete it. 6 When uninstalling unnecessary programs, you should select "Add/Remove Programs" in the control panel to confirm the deletion, which is the method to completely delete.
10, delete the Windows.old file.
1 1. If you are a user who upgraded Windows 10/from Windows 7/8, or installed a Windows system by performing a custom installation, and the partition was not formatted during the installation, the files used in the previous version of Windows are stored in the Windows.old folder. The types of files in this folder depend on your computer. After using the Windows system for a period of time (for example, one week or two weeks), if you are sure that the files and settings have been restored to the desired location, you can use Disk Cleanup to delete the Windows.old folder, thus safely recovering disk space.
12. Hibernation will occupy disk space, and turning off hibernation can also release some disk space. Please note that this "hibernation" function is not what we usually call "hibernation" function that notebook users may apply for. Hibernation is to write all the data in memory to the hard disk, and then shut down the system. The next time you start, you will write the data back to memory. The advantage of doing this is that the work you are doing will be saved, even if the power is cut off, it will not disappear, which is why people often say that they don't have to turn off their phones for several months. Most people don't use this function often, but they pay the same amount of disk space as memory for it in vain. If the capacity of your C drive is too small, we can turn off this function.
13, hibernation is a very power-saving and equipment-saving mode. It saves the data in the memory in the hard disk, so that the CPU stops working. When you use it again, you need to press the on/off key, and the machine will return to your hibernation state without the complicated process of restarting Windows, so it is best not to cancel this function unless absolutely necessary.
