TAB will only autocomplete one file for you as of Vim 7.4.282
use to autocomplete all files.

You can just use:

for example, you have 1.xml, 2.xml, 3.xml, and 4.xml, you can do:

bd xml

vim will autocomplete for you as follow:

bd 1.xml 2.xml 3.xml 4.xml

you can just press enter to complete the command.

if you have made changes in one of the files mentioned above, do remember to do:

bd! xml
