The disk space requirements for Windows 10 are high, as the minimum requirement is 16 GB for the 32 bit version and 20 GB for the 64 bit version.
I mention large because if you compare the space required by the Microsoft operating system with that with MacOS or Ubuntu the differences in space are also large when 9 and 5 GB are needed respectively.
Of course with the capacities that exist today, it is not a problem especially if you use xTB disks. But if your drive is an SSD at 32 or 64 GB you do not have such a large margin of waste.
Below we will see what features Windows 10 has to reduce the trace of your operating system.
Windows 10 Storage
With Creators Update, Windows 10 got a new auto-cleaning feature called Storage Sense. It does not do anything new, but it comes as a quality upgrade that essentially relieves you of the responsibility of organizing and deleting your files. To activate the function:
Open the "Settings" application.
From the System - Storage - Storage
Select the option
Compact operating system
Compact OS, or Compact OS, is a Windows 10 compression feature that reduces the total space of system files and applications in the Windows Store. When you turn it on, it will take a few minutes to compress everything. Once the compression is complete you will see that you have saved from 1 to 7 GB.
Caution Compact OS requires a little more RAM when accessing system files due to decompression.
Did you know that Windows can selectively compress individual files and folders while allowing you to use them normally? The feature is called NTFS Compression and can be a much better option than using an application like 7-Zip to compress and decompress the files you select.
From File Explorer (Windows + E) open any folder.
Right-click the file or folder you want to compress and select Properties.
On the General tab, click Advanced…
Enable the Content Compression check box to save your disk space.
Caution: With NTFS compression, files and folders will use more CPU when used, because they will need to be decompressed.
But you can use NTFS compression for infrequently used files (backup files, etc.).
Tip: Avoid compressing audio and video files because they are already compressed and also do not use NTFS compression for system files or folders!
Applications and media in external storage
The first major update to Windows 10 was the ability to install Windows Store applications on external storage devices, such as USB, SD cards, and external data units.
It also works with media files such as images, audio, video, etc. This can help you free up a lot of space on your main disk. But before you do anything, make sure you have connected an external storage device and set up the redirect of the above files:
From the "Settings" application.
System - Storage - Storage settings.
You probably do not use OneDrive, as there are many who do not use it. If you think about it again, Microsoft is offering a free 5 GB package for storing your files. Run the OneDrive app.
On the system tray, right-click the OneDrive icon and select Settings.
On the Account tab, click Folders.
Select the folders you do not want to sync and click OK.
Windows 10 Reserved Areas
There are three important features in Windows 10 that hold large chunks of your disk for data storage: Hibernate, System Restore, and Page File. The last (Page File) should not be disturbed. Let's see what we can do with the first two.
It saves a snapshot of your current status to a file called hiberfil.sys, and then suspends the screen, ports, data module, and RAM. This feature is useful when you want to get away from your computer for a few hours without shutting everything down. Recovery from hibernation is much faster than a normal boot
But the hiberfil.sys file is quite large - by default. It totals 75 percent of the total RAM. That is, if you have 4 GB of RAM, then the file will be 3 GB. This file is still there and to get rid of it, you need to turn off hibernation completely. But you miss the quick session reset in Windows 10.
Press Win + X together and select Command Prompt as Administrator.
To turn off hibernation, type: powercfg.exe / hibernate off
To enable inactivation, type: powercfg.exe / hibernate on
In Windows 10 there is no partition disk for system recovery. System Restore is a function that creates and saves snapshots of your entire system, which you can use to restore your system in the event of something going wrong.
The problem is that these snapshots take up a lot of space. Usually the space allotted is based on a percentage of your disk capacity. By default, Windows 10 holds 15%. So for a 500 GB hard drive, this space reaches 75 GB. You can of course reduce this percentage or turn off System Restore completely.
Caution: an average restore point requires about 600 MB. Keep enough space for at least five restore points (3 GB minimum).
Disk clean up
Cleaning your disk once a month can rid you of unnecessary files. You can run Disk Cleanup after each Windows Update.
When Windows updates, they keep a snapshot of your system before the update in case something goes wrong and you want to restore the system. These snapshots can be huge.
Start the Disk Cleanup application by searching for "Disk Cleanup".
Click Clear System Files.
Select the file types you want to delete. You can choose to clean Windows Update, temporary Internet files, temporary files, and the Recycle Bin. Just make sure the latest Windows Update does not indicate that there are any problems and that you do not need anything from the Recycle Bin.
If there is another way that is not listed above you can add it to the comments of the post.
