Currently upon browsing the data store of our vsan we saw weird folders in there that weren't in there before. Anybody have any idea what this is?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Not weird at all, completely normal and auto-generated witness folders for vSAN.

Are there VMDKs in there? Generally a real folder is named with GUID, while the symbolic link contains the folder name, for example, VMNAME
AMSDOTNETAuthor Commented:
Yes there are what appears to be the VM's config files and vmdk's. Here is another screen shot.
