• Suspect folder (hex characters in name) in /Library/ApplicationSupport

    From JF Mezei@jfmezei.spamnot@vaxination.ca to comp.sys.mac.system on Wednesday, June 09, 2021 15:14:45
    From Newsgroup: comp.sys.mac.system

    Found a odd folder in /Library/Application Support.

    each .dat file contains gibberish (no readable text).
    Some files from 2020:
    April 30,
    May 18
    August 25

    But one from:
    May 27 2021

    Any chance these would be legit (fearing some license files for Adobe
    products that are stored in non obviosu places) or are these nefarous
    and should be deleted?

    (I wish there were a feature like on VMS where you could set an alarm
    whenever a file is accessed so I could know when and more importantly
    which process opens to read or write such a file).

    there is nothing suspicious about that path, it's simply a hash value.
    They are not common in Application Support, but you will find similar
    pattern files troughout your library.

    $ find ~/Library | egrep "[0-9A-F]{8}-[0-9A-F]{4}-" | wc -l
    160820

    Yes, that is 160 thousand files or folders with the pattern of 8 hex
    digits, a dash, 4 hex digits, and another dash.

    Chances are that if you delete or move the folder, it will be recreated
    by whatever app you have that uses it.

    Get info on some of these provides no useful info? I have come to love Houdahspot for digging through my world.

    I might look at "all files created" on Aug 25 to see if I could find a correlation.

    There are apps like FSMonitor which will tell you when a file is created.

    There's a lot of strange named files and folders within the two Library folders, especially deep inside various sub-folders. You'll never find
    out what they belong to. You can thank MacOS X being based on Unix for
    that (there were strangley named files and folders even in the
    "Classic" MacOS System Folder, but nowhere near as many or so
    widespread).

    Another puzzling one, a behaviour I have not seen before.
    High Sierra. Home directory on APFS SSD.


    On my desktop:

    .MG-9A44E1BB-6071-4B4...91546D
    (icon is that of a vanilla document).

    I cannot move it in Finder.
    I cannot Alt move it to another folder to copy it. (to see what is
    inside, how big it is).

    If I move an item that is just to the right of the file, the mystery
    file then moves right to the space vacated when I moved the other file.

    I cannot Get Info for it. (no error message, but nothing happens).

    If I try to delete it:
    "The Item .MG-9A44E1BB-6071-4B43-B82D-D2828F91546D can't be moved to
    the Trash because it can't be deleted. (only button is OK)

    If I open a finder window to "Desktop", the file isn't there (but then
    again, I think Finder tends to hide any/all . files) imilarly, Time
    Machine does not show the file.

    In command line:
    ls -a ~/Desktop does not show the file
    ls -a ~/Desktop/.MG* does not show the file

    I can't run disk first first air without logging off. I get a feeling
    that there is an entry in the GUI file that contains desktop description
    and file positions, but that entry doesn't poinr to a file.

    or is there a way to hide a file from the unix side of things (eg:
    invisible to ls ?

    That will work with files that can be deleted. It is unlikely to work
    with a fle that reports it cannot be deleted. It is ossile that the uchg
    flag has been set for the file. you can celar it with:

    open terminal
    sudo chflags -R nouchg <drag the file in to the Terminal>

    then try to remove the file.

    However, since the Unix view of the file system did not see the file, I
    have to wonder if that command would simply return "file not found,
    can't be deleted" kind of message.

    Is there an "ls" incantation that would show any/all hidden files ?

    One way to see everything in a directory is to use the find command.

    If you cd in Terminal to the directory with the stubbon file, run this:

    find .

    or if it's a large directory (many files)...

    find . | more

    I dunno about the mac, finder and all that but there used to be a way of destroying a file via the inodes. The mac seems to support:

    ls -i filename

    which will return something like:

    57835797 zzz

    where that number is the inode the file starts at but they seem to have changed/removed the rm -i command which used to be remove the files inode
    and changed it to interactive.

    The osx find seems to support both the -inum and -delete so something like this:

    find . -inum 57835797 -delete

    could get rid of it.

    Keep in mind that will blow the file out but with Finder and a gui, it
    doesn't mean it'll disappear from the desktop.

    Odds are when you rebooted it ran fsck, figured the problem out and fixed things, that sort of is the point of it.

    Would the above list files that sudo ls -a didn't show?


    BTW, is APFS now suffiently documented to allow 3rd party apps to parse
    the APFS file structure , undelete files etc. Such an app might have
    been able to give hints on the existence (or lack thereof) of this file
    which appeared in Finder on Desktop but nowhere else.


    find . -inum 57835797 -delete

    Would it be correct to state that all the Unix utilities use the same
    interface to the Apple file system that synthetizes Unix file
    names/structure and so if ls doesn't know of a file, no other unix
    command would? or are there commands that have lower level access to the
    APFS file system?

    It's really a "more than one way to skin a cat" possibility.

    The main difference would be the find command would show the contents of a directory, if one is in the directory you are using find on, where ls is
    just showing the directory name.

    You also don't get any permission or ownership info with find.

    So it (find) could show something that ls isn't. Or not.

    I don't know the answer to that but one thing I haven't seen mentioned is
    that .DS_Store file. As far as I know, the osx finder reads from there to
    show what things are. I guess it's a mini database of sorts. Somewhere osx
    must scan drives, directories, files to create a fast way of seeing in the finder and make updates as things change.

    I'd guess from the original complaint that finder was showing something that didn't exist within the file system. The .DS_Store file maybe had some corruption.

    Wonder if the .DS_Store file was simply deleted and let the osx rebuild it wouldn't of fixed the problem also.

    Just pointing out that Finder (the gui) is not the same as looking at the
    file system through Terminal.

    No, the .DS_Store files contains metadata about the folder display
    settings for the finder window. Things like position on screen, list
    view, sort selection, dimensions, state of the sidebar, etc.

    It has no other function.

    It is impossible to guess with JF.

    Nope, it has nothing to do with files.

    Of course not, but JF lacks some very basic understanding and is
    constantly saying inane things about the filesystem that shows he is
    quite clueless about how it works.

    Reality is a curve. That's not the problem. The problem is that there
    isn't as much as there should be. According to some of the more
    mystical texts in the stacks of the library of Unseen University

    created lies outside the multiverse, and since the multiverse by
    definition includes absolutely everything that is anything, this
    puts a bit of a strain on things. --Moving Pictures
