I don't see it in Explorer...only when I do disk analyzer with ccleaner

It shouldn't show up there either, it doesn't appear for me in CCleaner's Disk Analyzer in 1903.

In all of the insider builds for the past year that I'm inscribed, ccleaner sees it..just wanted to.know what it was and if it counts towards the HD space being used

Must be an 'Insider' thing then, it doesn't see it in the RTM.

Yes, it will occupy disk space, but it shouldn't be much. There's more on NTFS metadata here....

NTFS - Wikipedia

...including a neat trick with 7-Zip File Manager to explore it (you need to run 7zFM as administrator). Unfortunately you can't use this trick to see $Extend on the active partition (so you'll need to boot something else, such as WinRE, to look at C:). But here's what I see on my D: drive.

@Steven Campoli,

I've just done that using Kyhi's rescue disk. Here's what I found on C: in another 1809 system. $Extend is about 20MB.

I have a question..if I download kyhis rescue disk would it allow me to delete that folder

Kyhi's rescue disk (or at least, the version I used) doesn't include 7-Zip. I actually ran 7zFM.exe from the C:\Program Files folder of the machine I was looking at.

In 7-Zip File Manager, when right-clicking on anything in [SYSTEM] such as $Extend 'Delete' is greyed-out. Probably just as well, you risk damaging your NTFS structure if you delete its metadata.

Ok so it's better I don't touch it...I usually know where my space is taken but I think I'm gonna have to let This one go. Thanks guys for responses

What I'm seeing is that the directory extend is getting larger and larger..from the last builds it keeps growing
