Why some folders are omitted in a MC window

[mc1cutas]

Hello folks,

In the screen capture attached, MC do not display two of the folders that are present (see Explorer window below). They are not marked as hide o something similar. Could anyone explain why this is happening?

Thank you in advance

Some folder must have the System or Hidden attribute set or they would be shown.

But you always can show/hide "hidden files and folders" and "system files and folders" in Configuration - Explorer panel settings... - Display tab - File and folders display - Show/Hide special files and folders
