Why does my C drive fill up easily?

It's normal. 1.Most software will create a cache directory or temporary file directory in the system partition.

When a program is executed, the system or the program itself will copy frequently used files to this directory, sacrificing hard disk space in exchange for running speed. Over time, even if you don't have any software installed, disk space will take up. This problem basically can't be solved, but it can still be properly solved through some software, but it will still happen over time.

2.Disk fragmentation, where files are stored on disk, is in the form of a cluster of files (seen as a container for storing data), a file cluster is a fixed size, can only hold a fixed amount of data, and when the data exceeds the size of the file cluster, it will be clustered.

To put it simply, for example, if each of your file clusters is 128k, when you encounter a file with 129k data, it will occupy 128*2=256k file cluster (there is 127k free), but when you encounter a 129k file again, it will not fill up the remaining 127k last time, but will occupy another 256k file cluster again, and will not store it until it encounters a file less than 127k. However, we know that file storage is random and not something you can control. When I encountered a 127k data, it was not necessary that the head could read the spare file cluster.

A large number of file fragments will result in a large amount of waste of file clusters. As a result, the space is getting smaller and smaller. This problem can be solved by defragmenting.

3.Virtual memory, if you set the virtual memory to the upper and lower limits (i.e., fluctuating), it will be like this, because the virtual memory is located on the hard disk, and it will not be cleared when it is shut down, if it is dynamic virtual memory, then it will get bigger and bigger, but it will not exceed the upper limit. If you care, set it to pin or move it to another section.

Because no matter whether it is installed in **, it has a certain connection with the C disk.

If the capacity of the C disk is full, it will seriously affect the operation of the system. Because Windows will constantly have temporary files and caches that consume the space of the C drive, if the capacity of the C drive is too small, there are several ways to choose:

One is to use the exorcist to increase the space of the C disk.

the second is to install the software to other drives; Set Windows cache, Internet temporary folder, Office temporary folder, and all other folders that consume C drive space to other drives.

1. Drive C is a system disk. When the system is running, it needs to exchange data with the hard disk, and when the memory is small, it will accelerate the data exchange with the hard disk. In this case, you need to write to and read a large number of cache files to the C drive. If the space of the C drive is too small, it will greatly affect the running speed.

2. When some software or games are running, they will also store cache files with the system disk. will occupy the space of the C drive. When the space is too small, it will slow down or make the game slow down or unable to run. The system will also become slower.

3. When surfing the Internet, a large number of cache files will also be generated, which will be placed in the system disk. Especially when the video screen is used, a large number of cache files will be generated.

4. Cleaning up garbage in time will speed it up.

5. You can change the location of the swap cache to other drive letters with large space. Keep it as little as possible in the system disk. The simple setup is as follows:

6) Change the second variable as well.

Normally, the C disk is a system disk. When the C drive is full, it will behave as follows at the interface level:

The C drive is red.

A warning will appear.

When the C disk is full, it will bring the following conditions:

The system is running stuck.

Some of the updates and files stored in the C drive by default cannot be stored normally.

The Windows update file does not install properly.

If there is something that needs to be installed on the C drive, it cannot be installed.

When the C disk is full, you can use the following methods to release the system disk space:

Use Windows native tools to clean up disks in the following ways:

Right-click on the C: drive, select Properties, and then click the Disk Cleanup button in the Disk Properties window. Right-click on the C: drive, select Properties, and click the Disk Cleanup button in the Disk Properties window.

In the Disk Cleanup window, select the files you want to delete, and then click on them"OK"。In the Disk Cleanup window, select the files you want to delete, and then click OK. If this doesn't make much space, you can click the Clean System Files button to delete the system files.

Thus being able to delete previously installed system files such as windows (folders), system restore points, ** stations, etc.

There is an official Microsoft help document for reference:

Free up drive space in Windows 10.

2.Delete the dormant file

Windows reserves about half of the RAM space for hibernation files. If your computer's RAM is 8GB, then the size of the hibernation file (is about 4GB.

Ways to delete files: 1

1.Enter"Get started"menu, enter"cmd", right-click the result command prompt, and select Run as administrator.

2.Then type" -h off"and press Enter.

After that, you should see a few gigabytes more free space on your system drive.

3.Use professional cleaning software

The easiest way is to install some professional cleaning software to clean up the system disk, and the more recommended is Cleaner One Pro. Of course, there can also be other options, such as CCleaner, etc.

Run junk file cleanup directly. This way, junk files that are taking up space on your disk can be scanned directly.

If that doesn't work for you, you can also use Disk Analysis. The Disk Analysis tool provides an interactive map of the relevant disk space usage.

You can clearly figure out what files and folders are taking up your C drive's storage space. This way, you can have the option to delete it in a targeted manner. Hope it helps.

There will be a little bit of a card, you right-click on the C drive icon, there will be a formatting option, if not, you right-click, and then press the A key, if it still doesn't work, just use the command. (Press the start key to run and enter cmd and enter format c: in the cmd command prompt.)

It is best to add the following parameters: q s means, that is, the quick format flower also has the system file when formatting. ）

You still have space to play the game, but you can't play it once it's full. c Do not format, once formatted, reinstall the system. Since the things in c are useless, you can delete the files, ** and other things.

programs, windows, system, things can't be moved.

Just move with a 360 C drive.

Transfer files, uninstall unnecessary programs, or merge partitions (not recommended).

Hello C disk space is occupied, resulting in system files running poorly, the system crashes, can't turn on, this situation is only to reinstall the system.

Detailed steps: 1. When the computer starts up at the beginning, press the [del] button to enter the BIOS. The English below the figure: press del to enter setup, that is, press [del] to enter the BIOS settings.

3. Then put the bootable disc into the optical drive, generally there is a win7 boot disk or winxp boot disk, and install the operating system according to the prompts.

4. After the installation is completed, enter the BIOS and change the boot sequence back to HDD (i.e. hard disk) as the first and CD-ROM as the second bit. The operating system is then installed.

What should I do if the C drive of my computer is full and the memory is insufficient?
