How to release C disk space in Win8/8.1 system to save valuable C disk resources

Many users who use Win8 and Win8.1 systems can easily find that the original system disk only takes up 30G. As the usage time increases, the disk space of the C disk decreases, and this part of the reduced space runs away. Where is it? How do we release the C drive space?

Due to the special environment of Windows system, the general reduced space is mainly concentrated in the following:

1, the registry: user data and program data are continuously written to the registry, so the registry is also Will get bigger.

2, patch installation: Windows Update automatic update opens, almost every month there will be a new patch release. Installing the patch requires extra space (the patch replaces some files and backs up the original files).

3, system restore: System Restore will automatically create a restore point, you need hard disk space.

4, App Store Cache: The app store will have residual cache file deposits when downloading apps, which will take up some space.

5, other temporary files such as hibernation and system-driven backup are also larger files.

2, after analyzing the disk status of the system disk, the situation of large files or file occupancy is also known, and then the system disk slimming operation begins. For example, the system slimming tool safely deletes system files that can be cleaned up.

3, Program Files or Program Files (x86) weight: used to store application installation directory, occupy a certain volume, a larger volume can offload some procedures.

4, ProgramData slimming: not recommended, store most of the application software and program configuration information

5, Windows system home directory: which stores the system Windows Update upgrade every month Various temporary files, including temporary caches generated after the app store app is downloaded. Support manual deletion or third-party tool deletion.

The specific path is as follows: C:\\Windows\\SoftwareDistribution\\Download

6. User personal data Users: It stores the temporary software files or the user's daily operation. Various temporary documents are not very large in size, but they can be accumulated in a long time. Since temporary files are system hidden files, they can be resolved using a third-party security cleanup tool.

7, a different restore point files directory Recovery: stored manually created or automatically generated restore point, it is recommended to adjust the upper limit is not recommended to close the function.

The operation is as follows: Right click on my computer, select Properties, and enter the system information summary page.

Then select the system protection function, the system is turned off by default. It is recommended to manually enable (enable) and configure the disk space usage.

8. System sys file generated by sleep hibernation

Since Windows 8/8.1 introduces the quick start function, it speeds up the booting speed. If the hibernation function is enabled, it will be in the system disk. Generate a system hibernation file pagefile.sys and hlberfil.sys file with large physical memory.

You can use powercfg /h on or powercfg /h off administrator: command prompt to enable or disable hibernation.
