So, I bought an SSD to upgrade the speed of my PC, and started transferring extranneous files over to a 10TB portable USB drive that I had. In this effort to reduce the size of my hard drive before trying to clone it to the SSD to make it bootable, I used the program SpaceSniffer to see if there's any other places on my hard drive that I could pull data from to reduce the size further, and to make my new SSD as "clean" as possible before the cloning.

Anyways, SpaceSniffer discovered the following folder:

Old HDD

Which is actually another "clone" of an even older terabyte hard drive that I'd upgraded from previously, and completely forgot about. Here's the thing though, I already have "Show Hidden Files and Folders" checked, and I'm able to see hidden files and folders. However, I am NOT able to see this folder for some reason: Hidden Files

The weird thing is, I CAN navigate directly to the folder and view its files by directly typing the path in the navigation bar: Old HDD Contents

Has anyone ever heard of this before, or can explain what's going on here? Also note the "read only" checkbox having a square in it, and the hidden checkbox being checked AND disabled in the very first screenshot above.

This seems to be a "super" hidden folder for some reason. And having used Windows since the 3.1 days, I've NEVER seen anything like this before. So, do any bigger Windows experts have any explanation for the strange behavior of this folder?

You will be much (much) better off to install your OS fresh on your SSD, add apps and recover data. That is a much better way to start cleanly and efficient disk space.

    Can you open a command prompt as admin, and type attrib in the C:\ and see what attributes the folder has? I suspect it has +S +H (system and hidden), so its seen as a system protected folder, which is different from a normal hidden folder. If this is the case, you should be able to make it visible in explorer by typing attrib -s "Old HDD"

    Can you run attrib /d to process directories as well, and tell me what Old HDD has?

    A stands for Archived. I'll write you an answer. :)

    I just realised your question says How to make "Super Hidden" folder visible, and attrib is -s -h. Even though -s stands for system, it might as well refer to -super -hidden. Yes, pun is intended here, but wanted to share. :)

In explorer, you can set "Show hidden files, folders, and drives", but there is another setting for "Hide protected operating system files (Recommended)". The latter one is usually enabled.

When a folder has the system and hidden flag set, it is configured as secured operating system file and remains hidden if show hidden files is turned on.

By typing attrib /d from a command prompt in the folder, you can see if this is the case.

See this example:

C:\>attrib /d
   SH                C:\$Recycle.Bin
     R               C:\Documents and Settings
A  SH   I            C:\hiberfil.sys
A  SH                C:\pagefile.sys
                     C:\PerfLogs
     R               C:\Program Files
     R               C:\Program Files (x86)
    H   I            C:\ProgramData
   SH   I            C:\Recovery
A  SH                C:\swapfile.sys
   SH                C:\System Volume Information
     R               C:\Users
                     C:\Windows

As you can see, the swapfile.sys, a system file has both +S and +H set, and thus it remains hidden unless you have the Hide protected operating system files (Recommended) unchecked in your settings.

The A stands for Archived, and the I for indexed. Type Attrib /? to get a full list of each letter.

In order to make the folder visible, you have to type Attrib -s -h "Old HDD"

Even though you can set the s and h individually, removing the s attribute also requires the h to be removed.

Also, explorer can set attributes on a file, but if you set it on a folder, the changes are usually ignored. With attrib, it just always works.
