The capacity of the C drive has become smaller after restoration, why does the C drive suddenly beco

My computer --- right-click --- manage --- disk management --- see if the space of the C drive is also 19G, if it is also 19G. You'll need to use the Partition Magician (commonly known as PQ) to get the lost ones back.

After reinstalling the system, generally only the system disk Chinese files (such as windows, program, documents and settings, etc.) like the programs you have installed before will be deleted from the C drive.

1. Many software installations use temporary folders, and some software will not automatically delete the files in the temporary folder after installation, so the free space of the C drive becomes smaller. You can open "My Computer--> Tools--> Folder Options--> View", check "Show all files and folders", press "OK", and then go to C: Documents and Settings Your username Local Settings Temp, and delete the files inside.

Second, the system restore function to automatically back up some information of the system, but also take up a lot of space. If you don't need this function, you can go to "Desktop -> My Computer -> Properties (in the right-click menu) -System Restore", check "Turn off System Restore on all drives", and finally press "OK".

Third, the virtual memory of the system also occupies a certain space, which is unavoidable. Some software has a dynamic link library file (*.dll) must be installed in the system disk, and the software will also write some information to the system disk, which is also unavoidable.

As more software is installed, it is inevitable that the free space of the C drive will decrease.

1.If the machine memory is large enough, such as 6G, 8G, etc., there is no need for virtual memory at all, so right-click the computer - Advanced System Settings - Advanced - Performance - Settings - Advanced - Change, remove the automatic management check, click no page file, click Settings, OK, Restart, or change to another partition, just click on the no page file, and then click D disk after setting, click the size of the system management, click Settings, OK, restart. Reduces occupancy by about 8g.

2.The auto-update cache file can be deleted, C: Windows SoftwareDistribution Download, which can be deleted, but it is best to turn off the auto-update after the update is completed.

Reduce the footprint by a few hundred meters.

3.System Protection can also be removed, right-click on the computer, Advanced System Settings - System Protection - Configuration - Disable, Delete, OK. Approximately 4G less occupied.

4.To hibernate a file, you need to use a command first, win x selects the administrator command line, and enters powercfg -h off, which can reduce the occupation by about 6G.

5.Index files can be deleted or transferred, so it's better to transfer them in order to preserve functionality. Control Panel, Index Options Advanced > Select New Location > OK OK.

This way the index file is transferred, and if you don't want the search function, then delete it. The way to do this is to find Windows Search with Win+R input, select Disable, and then find a very large file in C: ProgramData Microsoft Search that can be deleted.

6.Desktop files, very simply, transfer or delete!

Why is the win7c disk space getting smaller and smaller.

That's for sure, if you patch it, it will take up space on the C drive, we can make you feel that the C drive is smaller and you can hardly feel it, 1. You have to turn off the system restore. The sleep of the computer is also turned off,This you can rest assured that it will not affect the normal use of the computer,Finally, you use 360 security experts to help you clean up the useless junk files of the C disk,It's OK。

Open the My Computer, Tools, Folder option, View, tick "Hide Protected OS Files (Recommended)" and.

Select the "Show all files and folders" radio button, click the "Apply" button, you can see the hidden files, it is recommended to use Optimizer to clean up junk files.

Clean up the system junk... Check the documents of the C drive. Take a look at how big it is. Then step by step to find which one is the largest. Most of them are temporary documents.

Your C drive memory is getting smaller and smaller, and the possible reasons are as follows:

1.You install a lot of apps and software that take up a lot of space.

3.**The station was not emptied in time, and a large number of junk files accumulated inside.

4.The computer system is updated and patched, and temporary files are generated, which occupy the space of the C drive.

How to solve this problem?

1.Uninstall some apps and software that you don't use frequently to free up space.

3.Empty the ** site regularly and delete unnecessary temporary files and junk files.

4.Use the built-in disk cleanup tool to clean up temporary files and other unnecessary files from the C drive.

Keeping your computer tidy and cleaning up unnecessary blind shed files can effectively free up space on the C drive.

The reason why the space of the C drive is getting smaller and smaller:

As the system disk of the computer, it is not an exaggeration to describe the C disk as the heart of the computer. Since the operating system of the computer is located in the C drive, once it runs, it will produce a lot of junk files, so whether you use it or not, the C disk space will get smaller and smaller to a certain extent, so it is normal for the C disk space to get smaller and smaller. As for the reasons that cause the space of the C disk to become smaller and smaller, the following aspects are summarized for you:

1.For the ** station on the computer, this will be the first reason why the space of the C disk is getting smaller and smaller. When we delete some files on the computer, these files will be temporarily stored in the **site,If we do not completely clear it,This part of the temporarily deleted files will occupy the space of the C disk,Usually the more files that are not completely deleted,The more space it occupies in the C disk,After the files temporarily stored in the ** station are completely deleted,The space of the computer C disk will also increase accordingly。

Of course, there is also a problem to note here: usually the default of ** station is 10% of the disk

2.The second reason is that you need to check whether your computer has disabled the setting of System Restore, because the system restore setting will reduce the space of the C drive to a certain extent, so if you find that it is not disabled, please disable this setting immediately.

3.The third reason has to do with page files and virtual memory. Generally speaking, the page file is relatively large, if the page file is stored in the C disk, and in the same period of time because of the need, a lot of programs will be called, it will make the page file continue to expand, which will make the computer virtual memory reach a certain limit, so you need to call the task manager at any time to check whether the computer's memory is about to be consumed, if so, it should be transferred to other disks.

4.In the case of temporary files, this will be the fourth reason why the memory of the C drive is getting smaller and smaller. Generally speaking, there are two ways to create temporary files, one is the Internet, and the other is the files in the temp folder in the same directory.

However, it is recommended that you use the built-in disk cleaner of the C drive system to clean up such junk files, because this will not delete files that should not be deleted by mistake, which greatly avoids the degree of manual operation.

5.Installing software is something we can't avoid, and it's the last reason why the C-drive system is getting smaller and smaller. Although sometimes you choose to install the software on other disks, don't forget that there are a lot of items to register when installing a software, and you can put it in the system folder, and the files that need to be called are also very large, which will cause the space capacity of the C drive to become smaller and smaller.

That's why it's recommended that you don't install too much software on the system disk.
