I have a 1000 gig Windows SATA HD
I don't want to Delete the Windows installation in case I sell this HardDrive with he pC it came with.
Using Gparted, on by Ubuntu 17.10 PC running from a SSD drive, I Shrinked the 1000 SATA hard drive so the Windows in left untouched
Created a 400 Gig partion EXT4
And I can't create Folder within this partition but can see it from the FileManager
