All types of access are denied. Also, setuid, setgid, sticky bits are cleared

Root can access that file

Later he can change permissions of that file

Owner of that file can access that file too but after chaging permissions.

If a file has permissions 000, then only system administrator or super user can access the file.
When the file or directory is created, then initially the default permission creation of ALL FILES AND DIRECTORIES ARE :

PERMISSION OF FILES: 666(~rw-rw-rw-)
PERMISSION OF DIRECTORIES : 777(drwxrwxrwx)

If file has permission 000,
then mathematically it means that 666-000=666 permission means only accessed by super user but will not get execute permissions.
Owner of that file can access that file but after the permissions being changed.

When a file or directory is created the default permisions inherited .they are
for files :666
for dir: 777

Actually it is not the file permission .
the "umask" value is subtracted from these default permission.it is set by superuser.
$umask
0022
so,file permission wil be 666-022=644

In our problem the permisions become 000
so the umask value should be 666
666-666=000

The read write exec permissions of the file are 0.so it cant be acceble by any user.
To acces the file ,the owner or superuser should change permission by  using command chmod

chmod a+rwx filename

If all you want to do is get rid of that file, as I did, just save a known file, like a dummy text file, with that same name and overwrite the existing file. I replaced my errant directory file with a text data file of the same name, it overwrote the previous file, and it had new workable permissions, so I could then delete it. Kind of brute force, but hey, I had to do it.

If file has 000 permission, root user can read the file but cannot modify until he modifies permission

You cannot access the file with 000 permissions.

Root user can see and modify the file. Below are the steps -
1 > vi filename.txt
2 > change the contents
3 > :wq! (for forcefully edit)

This setting keeps the files useless; you cant do anything with it. But the user can still delete this file.
