Nowadays, computers have become an integral part of our lives and work. But the longer the computer works, the more we can perceive that the C drive indicates insufficient memory. When the C drive that is equivalent to the human heart, runs out of memory, countless operational problems will follow, such as computer crashes, card freezers, etc. These problems upset many users. You might haven't downloaded anything; how will the space of drive C be getting smaller? Don't worry. We will explain why the C drive space is becoming smaller and smaller. In addition to providing solutions for these causes, we'll also teach you how to move space from D drive to C drive on Windows 10/8/7 in two ways with a partition magic software -EaseUS Partition Master. With this tool's help, you can transfer space from D drive to C drive directly without any data loss.

Why C Drive Is Getting Smaller

In general, the C drive is the system disk on a computer. When the Windows operating system runs, it will generate a lot of junk files. Whether you use it or not, the C drive space will become smaller to a certain extent, and you can even see C drive shows red bar. There are many reasons why the remaining space of C drive is becoming less and less. The following aspects are summarized for you:

1. Files in the recycle bin take up space. The more data stored temporarily in the recycle bin, the more space on the C drive will be taken up. You can delete the files in the recycle bin, then C drive space will increase accordingly. You can recover deleted files from emptied recycle bin if you remove them mistakenly.

2. Is system restore enabled on your computer? The system restore setting will reduce the C drive's space; you can disable it if not necessary.

3. Page files and virtual memory. The page file is relatively large. If the page file is stored in the C drive, it may make the computer's virtual memory reaches a certain limit. Therefore, you need to run the task manager at any time to see if the computer's memory is almost exhausted. If so, you should transfer the page files to another disk.

4. Too many temporary files. You can use the disk cleaning program that comes with the C drive system to clean up junk files because this will not delete the files that should not be removed by mistake. See how to solve there is not enough space on C drive.

5. Installing software to the C drive will definitely consume memory. Although sometimes you choose to install to other disks, the relevant registration files will be placed in the system folder, which will cause the capacity of the C drive to become smaller and smaller. So, install applications outside of C drive, such as to the D drive.

If you have tried the solutions mentioned above, but the C drive still doesn't have enough free space; however, your data disk, such as the D drive, has a lot of available space, then why not try to move free space of D drive to C drive to extend?
