Trying to free up disk space

[antares]

Hi all, I will be cloning my main OS to a smaller size SSD so I'm forced to free up space.
1) I see a folder called "System Volume Information" , size 105GB, with a bunch of files dating back to Septembrer 2015. Are all these files necessary?
2) I see a "hiberfil.sys" in the root C, size 25.5GB, but I never use hibernation (I think I have it disabled). Can I shrink this file size somehow?
3) I see inside the C:\Windows\LiveKernelReports a Winsock*.dmp file size 3.46GB, is it necessary?
Any other tips? Thanks

System Volume Information holds your system restore points for one. Some info here: How to gain access to the System Volume Information folder

If hiberfile.sys is still there then hibernate is not truly disabled. Enter powercfg h off from a Elevated Command prompt. That should get rid of hiberfile.sys.

I don't believe anything in C:\Windows\LiveKernelReports is needed. Mine has the following:`

>dir C:\Windows\LiveKernelReports\* /s
 Volume in drive C is Lenovo_C
 Volume Serial Number is E065-4E60

All are dumps from one time or another.

Thanks Ztrucker,
-applied your suggested command and the hiberfile.sys is gone, 25GB gained , it seems hybernation was not disabled.
-I checked the dumps folder, only one dmp file dated april 2015, seems safe to delete, haven't done so yet.
- Most amazing of all, I turned off system protection and gained a whopping 106GB!!!

Now you can no longer use System Restore. Not a problem if you do regular image backups. If not it could be a problem when (not if) you have a future problem

 

[antares]

Yes, I seldom use System Restore as I do complete image backups monthly. On top of that, I allocated 105GB disk space for system restore, crazy. I only turn on system restore temporarily whenever I install new software, once I verify the system is stable without issues I disable it. For some reason I left System Restore and Hybernation on for a long time.
