If Vim has doubt about what it found, it will give an error message and insert lines with ??? in the text. If you see an error message while recovering, search in the file for ??? to see what is wrong. You may want to cut and paste to get the text you need. The most common remark is ???LINES MISSING. This means that Vim cannot read the text from the original file. This can happen if the system crashed and parts of the original file were not written to disk. Be sure that the recovery was successful before overwriting the original file or deleting the swap file. It is good practice to write the recovered file elsewhere and run diff to find out if the changes you want are in the recovered file. Or use |:DiffOrig|. Once you are sure the recovery is ok delete the swap file. Otherwise, you will continue to get warning messages that the .swp file already exists. {Vi: recovers in another way and sends mail if there is something to recover}\0";
