What is $Extend folder Windows 10

[roger_hawke]

Ran WizTree and $Extend showed up as can be seen in attached.
Not seen this before - what is the purpose - can it be safely deleted??

Rustys,

Thanks for that.
I guess it’s probably best to leave well alone, unless I wish to do a clean install of Win 10.
Would you agree?

[Rustys]

That is correct best to leave it alone and even if you do a clean install of Windows 10 there is no guarantee that it will not appear again some time down the road.
