    Hi there! My website has pulled up over 1000 instances of Unknown file in WordPress core. All of them are files that include “._” at the beginning of the filename or folder name.

    When I view the file, here is what I see: Mac OS X 2��ATTR��F�Fcom.apple.quarantineq [plus some numbers and characters I have redacted]

    This seems like the same issue here, so I think I can delete these files after backup. My only question is if I should be concerned about deleting files that don’t seem to correspond to an actual file in my File Manager. For example, WordFence found the file “._comments-popup.php” in the WP core, but I don’t have any file called “comments-popup.php” in that same folder. Thank you so much for your help!

  • Hey @kristengunther,

    Please do definitely take a backup before removing any files just_in_case.

    This is a WordPress Core file. The fact that it has “._” means it has been disabled, possibly a hosting back up. What does concern me is that there isn’t an active comments-popup.php file. Can you please share the path where you’ve found the disabled file? It should be in wp-includes > theme-compat.

    Please let me know.

    Thanks,

    Gerroald

    Hi Gerroald,

    Here is the path provided to me from the WordFence report:

    Unknown file in WordPress core: wp-includes/theme-compat/._comments-popup.php

    Let me know if this is what you are referring to, or if I can provide something else.

    Another example is:
    Unknown file in WordPress core: wp-includes/js/tinymce/skins/lightgray/fonts/._readme.md

    I could not find any file called readme.md in that folder in my File Manager.

    Thank you!

    @wfgerald I wanted to circle back on this support topic for any further guidance. Thank you!

    Hey @kristengunther,

    My apologies, I thought I had responded to you.

    I did speak with the developers about this, and they believe you’re correct in the reference to the other thread you shared. Here’s part of our conversation.

    AFAIK ._<filename> files are OSX Resource Fork files ( = metadata) viewed on a different filesystem than OSX one. They could have copied the website from an OSX-made archive file, or copied them uploading the website via the Finder (IIRC).

    And they agree with this assessment you shared.

    https://wordpress.org/support/topic/many-unknown-files/

    So, I believe it’s okay to remove them. But please do make sure to have a backup just_in_case.

    Please let me know how it goes.

    Thanks,

    Gerroald
