(1) Another program may also be editing the same file.
If so, be careful to avoid creating two different versions of the same file when you modify it.
Exit, or proceed with caution.
(2) Crash when this file was last edited.
If this is the case, please use ": Recover" or "vim-r exportcert.cpp"
Restore the modified content (see ": Help Recovery").
If you have already recovered, delete the swap file ". Exportcert.cpp.swp"
To avoid seeing this message again.
