Help: Non-existent user displayed

Ok, I'm here and without any good news :'(

I did all and now I have:

1) The whole partition F:\ is still considered as Pictures folder and if I try to relocate it I have this "warning" as yesterday.



2) The folder Pictures created yesterday with the batch file in partition F:\ is still there and is a system Pictures folder as before.



Look at the date and icon for both Hdd and folder



3) In User folder I have now another Pictures folder




And still I have TWO different User with different System Pictures folder (look the icon and name)




What could happen performing the move with the warning that I posted above ?
It's seems the last chance I have....

I'm getting mad!

Now the situation is worse than before.
I've tried all without any changes so I decided to do something decisive.
I've moved all the pictures in an external drive to backup them all.
Then I formatted the partition F: \
It did not do even that, it continued to remain as a folder and not as clean partition of HDD.
Then I deleted the partition AFTER running the "Restore to default" of the entire partition still seen as the Pictures folder even if it is empty and formatted. And this time no warning at all.
Actually I don't have a partition F:\ and I want to solve the problem before create newly and moving there system Pictures folder.

BUT:
If I click on the Pictures folder on the taskbar, it opens a folder whose name is F:\ and not Pictures, but it seems to be in C:\Users\BigBear\Pictures\.
But it is NOT there.
I cannot only post screenshot because the reality is absolutely absurd.

Look the screen and tell me how I can have newly my Pictures folder if you can !!

I've tried some trick founded on Reddit and now I have the right neme on the folder Pictures, with the right icon.

I have it in library, in the taskbar and in Quick access too.
It seems back near normal except of one thing: the system Pictures folder is not in User folder!!
Or, it's there but it's a hidden system file !!!




Now I have to understand why it's an hidden folder in User but it's visible as Pictures folder in explorer.
And I need to make it visible.... The properties are the usual properties, with the Location choice, sharing, security and so on.
But the "Hidden" attributes is checked and is grayed out.

Can anyone offer me any advice for the above problem please?
Dear Brink, are you completely exhausted by now about my problems?


I'm still with the Pictures folder grayed out and I don't want to proceed with the creation of the new/old partition and the relocation of the Pictures folder till I've solved that problem.
I'm not even sure if I can move that folder in the new location

Shawn, you are so kind: thanks again for all.

OK, I did the xommand and the Pictures folder is now unhidden.
But it's visible only if I enter in the User folder through C:\ --> Users --> BigBear and the folder is there and visible



but if I go there level by level (going up) I jump in BigBear Lio and there the folder Pictures is still grayed out.
And there are other difference between the two user's folder: the folders I moved in other location are not present in BigBear, but they are there in BigBear Lio!



My concern now, is that If I move the visible Pictures folder where it should be (partition F: \ that I'm going to recreate) it will re-create the problem of duplicate folder Pictures precisely because of that double name BigBear and BigBear Lio that despite being the same person, are perceived as two different user.
As you told me BigBear is the user profile folder name and BigBear Lio is the full name for that account, so the account is only one and is BigBear.
But then, why apparently the two folders are different and they are equal only if they are opened at the same time?
How can I fix that problem? Can I change the name?

Thanks so much for your patience!
