Why leave a certain amount of space for the C drive

According to experts' analysis, the optimal capacity of the C drive is 8G, and the C drive will cause the system to boot very slowly if the space is too large or there are too many applications.

The C disk is generally only used to install the system, and other applications are installed in other disks.

If you have a full C drive, no matter how much space you have on the C drive, all the temporary files are on the C drive by default.

To alleviate the space problem of the C drive, you can consider changing the temporary files to a different directory. Here's how:

IE Temporary Files:

Open the Internet option Temporary Internet Files to set that for your new directory.

Windows Temporary Files:

Open the My Computer Properties Advanced environment variable.

Change the tmp,temp variable inside to the directory of your temporary folder to clear some restore points:

Open the C drive properties Disk Cleanup Other options System Restore Cleanup This way there should be no more problem of insufficient space on the C drive My C drive space is 8G

In addition, you can set the virtual memory to a different disk

Because the general virtual memory file is placed on the C drive.

Ordinary people don't change its path.

So the system disk has to leave space for the virtual memory file, because the virtual memory file size changes.

The C disk is the system disk, the C disk only puts the things of the system, and the rest is put on other disks.

Because the risk of splitting the disk when the system is occupied, it is recommended to use the time dividing disk when reinstalling the system, and the common operation method of the subdivision area is as follows:

1. First turn on the computer, enter the desktop, and select "This Computer" to enter the file management meditation and closure.

2. Find "Computer" next to the file and click to open.

3. In the new toolbar, find "Manage" and click to open.

4. After opening the management page, find "Disk Management" at the bottom left of this page.

5. After clicking, the disk analysis bar appears on the right side, and find the C drive.

6. Click the right mouse button, the drop-down bar appears, select "Compress Volume" and click Zhipants.

7. The compression dialog box pops up, enter the space you want to compress in the input box after "Enter Compression Space", and click "Compress".

8. Right-click the "Unallocated" space obtained by the previous operation, and select "Create Simple Volume" to open the "Welcome to Create Simple Volume Wizard" dialog box.

9. Finally, in the newly popped-up format partition operation box, click "Format this simple partition according to the following settings", and click OK to complete.

To divide disk space to other disks:

1. Right-click on the computer icon on your desktop and select Manage Options.

2. There is not enough space for disk D, and there are many disk E, so we right-click on disk E and select Compress Volume; Please note that it is a dual hard drive, and it is only possible to divide the hard drive into d and e in the same hard drive.

3. The emergence of compressible capacity, free 150g can only compress 60g. The volume can't be compressed beyond the point where any immovable files reside. That is to say, there are some files in the C drive that occupy this part of the space, and this part of the space is obviously free.

In fact, this is the system's self-protection, or the system's default protection.

However, a maximum of 60G will be enough, it will not work, click "Compress" and start compressing the allocable space of the base.

4. At this point, I regret seeing the unallocated free space around 58G, then click on drive D and right-click to select Expand Volume.

5. Click Next when the wizard appears, then review the available space, and then click Next.

6. Show Done, click the Finish button.

7. Since the small D disk is the first partition disk of the mechanical hard disk, when the disk is expanded, there will be a prompt to make the basic disk a dynamic disk, if the C disk has a system, it is recommended that you do not merge, if not, then all are called.

8. Finally, click on it again, and the disk is divided.

Files have the drawbacks of C disk:

1. Everything is installed in the C disk, which will cause the system to be bloated and the response speed of the Qianhui system to be slow.

2. Everything is installed in the C drive, and the junk files and cache files generated when each software is running will have a bad impact on the system, which will seriously cause the system to fail to start.

3. Everything is installed on the C drive, which will increase the probability of the system being infected with viruses and rogue software. <>
