Win7 C disk expansion: How to expand the C disk of Win7 system?Importer data As a classic operating system, the performance of Win7 is obvious to all. However, with the increase in frequency of use over time, the C disk space of the Win7 system may become tight.At this time, it has to be expanded. This article will focus on how to expand the C disk of the Win7 system. Why do we need to expand the C disk of the Win7 system? When installing the Win7 system, set the C disk as the system disk, so all files, software and drivers must be stored in the C disk. After the successful upgrade of the Win7 system, a large number of temporary files will be generated. Coupled with the installation, download and update of various software, the space of the C disk is gradually becoming tight. If the C disk space of the Win7 system is insufficient, it may cause the system to crash, crash, slow operation and other problems. Especially when the space of the C disk is only a few G, and it is difficult to store the files and software required by the system, it is even more necessary to expand its capacity. Specific method of C disk expansion of Win7 system Method 1: Use the built-in Win7 systemDisk management tool Step1: Open disk management, find the C disk that needs to be expanded, and prepare the disk without partitioning. Step 2: Right-click on the C disk that needs to be expanded and select "Extended Volume". Follow the prompts to expand the space of disk C. This method is very simple, but it is only applicable when there is still an empty disk behind the C disk. Method 2: Use a third-party disk management tool Step1: Download and install the EaseUS Partition Master software. Step 2: Open the program, right-click the C disk that needs to be expanded, and select "Resize/Move partition" in the drop-down menu. Step3: Move the boundary line of the C disk partition outward to expand the space of the C disk. You can also free up space and expand the C disk by narrowing the space of other partitions.Step4: Finally, click "OK" to apply the change. This method is not only applicable to Win7 system, but also to other versions of Windows operating system. And you can make your own capacity expansion plan on demand. Method 3: Use the command prompt to expand the C disk Step1: Press the Win+R combination key, open the running dialog box, enter "cmd", and press the Enter key to enter the command prompt interface. Step 2: Enter "diskpart" and press Enter. Step3: Enter "list volume" and press Enter. This will display all the disks and volumes installed on the computer. Step4: Enter "select volume X", where "X" is the number of the volume that needs to be extended to disk C.Step5: Enter "extend size=Y", where "Y" is the capacity that needs to be added to the C disk. Step6: After the task is completed, enter "exit" to exit the command prompt. It should be noted that there are certain risks in using the command line to expand the C disk, and it is recommended to use it carefully. The above is a summary of several ways to expand the capacity of the C disk of Win7 system. However, before expanding the capacity, you must back up important files and data in the system in advance. Moreover, we suggest using a safer way to expand the system capacity. After the expansion, we need to clean up some useless files and software, especially those that take up a large amount of space. Only in this way can the Win7 system run more smoothly and users have a better user experience.
