"Super" Hidden Dossier?

ayi

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 disque dur before trying to clone it to the SSD to make it bootable, J'ai utilisé the program SpaceSniffer to see if there's any other places on my disque dur 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:

Quel is actually another "clone" of an even older terabyte disque dur 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 fichiers cachés and folders. Cependant, I am NOT able to see this folder pour une raison quelconque:

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

Quelqu'un a-t-il 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 pour une raison quelconque. 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?

In explorer, vous pouvez set "Show fichiers cachés, 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 fichiers cachés is turned on.

By typing attrib /d from a invite de commandes in the folder, vous pouvez voir 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 vous pouvez 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, vous devez type Attrib -s -h "Old HDD"

Even though vous pouvez 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.
