The free space on my computer s C drive is decreasing by 15

It seems that you don't show all the hidden files in the C drive, it is better to show "Hide protected OS files" as well, so that you can see what files are taking up space.

And it's best to set the "virtual memory" to another disk, "virtual memory" can at least add a lot of space here; The system's built-in restore function has also been canceled, and the sleep function has been canceled, so that a lot of space can be added after setting.

I've also had the problem that the remaining space on the C drive keeps getting smaller, because when I use Real to watch movies, C: Documents and Settings Administrator Application Data Real RealPlayer Temp

There are a lot of temporary files under the folder, and they are very large.

Just clear it up.

I don't rule out the possibility that your computer is poisoned, so it's hard to reinstall the system! It's not hard anyway.

Don't put system patch backup or anything on the C drive.

Check them all and see that there is no need to put the things in the system are unloaded and installed on the D disk, I want you to say that the situation must be that you installed the software carelessly.

The easiest, redo the system directly, or it will be tens of megabytes of space, and the system will run slowly.

<> you will find that the disk space is getting smaller and smaller when you use the computer for a long time, what should I do if the C disk space is insufficient in serious cases? In fact, this is because we usually install too much software, so it occupies a lot of C disk resources, resulting in the system running jammed, and it will crash in serious cases. The solution is:

Migrate your computer's software to a different disk and avoid installing too much software. There is also a cleaning up temporary file, look for it slowly in the C drive, you can find a lot of usual files, such as**and**, delete it when you find it. But be careful, don't delete the English folder and some configurations that you don't know in the C drive, even if it's large.

If you delete it, a software or computer system may not function properly.

How Do I Expand the Space of the C Drive as the Available Space of the System Disk Decreases? Take Windows 10 as an example; First, manually delete the virtual memory files automatically allocated by the system, which can generally free up 6GB to 8 GB of space, delete the default virtual memory space of the system, and manually set the virtual memory to other disks other than the C disk after restarting; Second, you can use third-party software, such as 360, to clean up large system files, there is another noteworthy place here, that is, you can delete the system's hibernation files through 360, completely close the hibernation system, the size of the hibernation file, as long as the computer running size and memory size are the same, assuming 16 GB of running memory, the hibernation file size is roughly between 16 GB and 20 GB, so you can close it manually or by a third-party software, delete the hibernation file, after deletion, The system disk can free up 16 GB to 20 GB of spaceFinally, if you are installing Windows 10 system, it is best to turn off automatic updates, which will not only take up a lot of space on the C drive, but also generate system cache files.

In fact, this is because we usually install too much software, so it occupies a lot of C disk resources, resulting in the system running jammed, and it will crash in serious cases. The solution is to migrate the computer software to a different disk to avoid installing too much software.

If you delete it, a software or computer system may not function properly.

If the C drive is insufficient, there are two solutions, the first is to expand the capacity of the C drive and install memory modules. The second way is to delete some unimportant files in the C drive.

When using the computer, be careful not to download too much software and junk files, and you can clean up frequently and uninstall unwanted software.

If the C disk space is insufficient, you can clean up some memory and junk inside, and you can also uninstall some unused software, so that's it.
