I have a "haier laptop y11b" it have 2 disks:
- SSD card of 29 GB, C drive on which windows 10 is installed
- HDD 465 GB
Previously Windows 8.1 was installed on this laptop and all the apps were installed on drive D. It was fine, showing no problems. There was always 13 GB or more free space available on C.
Then I installed windows 10. After installation on drive C, 15 GB was still free.
Then due to low space on C, I installed all of my apps on drive D, but space was still occupied on drive C. And now only 938 MB is free on C, and its marked red with error "low space on c".
Now I don't understand what is consuming drive C's space in windows 10, while there was no such problem with windows 8.1. How do I free out the space on C, while only windows 10 is installed there?
I downloaded WinDirStat and scanned C. I found a few large folders and files:
- Windows\WinSxS = 8.0 GB
- Windows\Installer = 3.1 GB
- ProgramData\Package cache = 1.2 GB
- pagefile.sys = 1.4GB
- hiberfile.sys = 803MB
Can I delete or move any file to other drives just to free up space on my SSD?
Best Answer
pagefile.sys
is an important Windows file. Delete that, and your computer won't restart. So you'd rather not delete it. ;)This article explains WinSxS: http://www.thewindowsclub.com/winsxs-folder-windows-7-8
So basically, there is a way to clean the WinSxS folder. You might want to run the
Disk Cleanup
tool that comes with Windows or download a cleanup tool, such asCCleaner
. From there, do not forget to uninstall useless apps and delete files you do not use.There is also ways to tell your computer to install every apps automatically on your drive D:.
Assuming you are using a Windows 10 64-bit, make this change as well:
regedit
and press Enter key.HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion
ProgramFilesDir
,ProgramFilesDir (x86)
to the new path.Little reminder
