They are NOT associated with files though. They are associated with a buffer.
The buffer is associated with a file, but you cannot use the marks for that
file unless you have that file in a buffer. The next time you create a buffer
for that file, Vim restores the marks from your .viminfo file if you told it
to, but you still can't use them if you're in a different buffer. Uppercase
marks are different. You can always load a file from an uppercase mark, whether
or not you have a buffer for it.
Just under :help :delmarks:
Lowercase marks 'a to 'z are remembered as long as the file remains in the
buffer list. If you remove the file from the buffer list, all its marks are
lost. If you delete a line that contains a mark, that mark is erased.
Lowercase marks can be used in combination with operators. For example: "d't"
deletes the lines from the cursor position to mark 't'. Hint: Use mark 't' for
Top, 'b' for Bottom, etc.. Lowercase marks are restored when using undo and
redo.
Uppercase marks 'A to 'Z include the file name. {Vi: no uppercase marks} You
can use them to jump from file to file. You can only use an uppercase mark
with an operator if the mark is in the current file. The line number of the
mark remains correct, even if you insert/delete lines or edit another file for
a moment. When the 'viminfo' option is not empty, uppercase marks are kept in
the .viminfo file. See |viminfo-file-marks|.
------------------------------
Here it specifically says lowercase marks are lost when you remove a file from
the buffer list.
It says nothing of the sort for uppercase marks, referred to in the same
section as "file marks".
:bwipe removing lowercase marks is well documented and intentional. Removing
uppercase marks is not documented and probably unintentional.
The way to remove all marks from a buffer, including file marks, is using
:delmarks. Otherwise, true file marks should remain. :bwipe doesn't mean "I'm
done with this file forever" it just means "I'm done with this file for this
edit session."
You can individually turn on and off saving lowercase marks. If ANYTHING AT ALL
is in the viminfo option, uppercase marks are preserved. This tells me file
marks are meant to be more persistent than the lowercase marks. Right now they
are not.
