Unable to create USB Boot Disc

Question

Unable to create USB Boot Disc

I am using MBP 13 2012, currently on Yosemite 10.10.5 .

After I download High Sierra from App Store, there is a folder inside my Applications - Install macOS High Sierra 19.9MB .

Then I saw a new folder "macOS Install Data" after I click on Macintosh HD with content 5.16GB

AppleDiagnostics.chunklist

AppleDiagnostics

BaseSystem.chunklist

BaseSystem

index.sproduct

InstallESDDmg.pkg

InstallInfo

OSX_10_13_IncompatibleAppList

If I remember correctly after finish download from App Store it should appear inside Applications folder Install macOS High Sierra with content like 5GB , why its only 19.9MB ?

How can I create a USB bootable with this ?

MacBook Pro, OS X Yosemite (10.10.5), null

I don't believe that folder's contents will be usable. I suggest deleting it as well as the Install macOS High Sierra file in Applications, and downloading HS again.

Something is not right.

Delete and download again, the installer should be 5.19GB
