If you are sure that is the only difference, you can just copy the
'format' file from another directory. 'branch-name' and 'parent' should
be optional.

But what concerns me is why something would be deleting your 'format' files.

Could it be an overzealous virus scanner? (I would assume it would
delete all the other ones, to). Or maybe a recursive delete gone wrong?
(find . -name format | xargs rm). I realize you wouldn't use 'find' on
Windows.

the .bzr/branch/format file isn't something we change often. I'm pretty
sure we write it at 'init' or 'branch' time, but then only read it from
then on.
