But, that had some problems. The main one is that some users want to be able
to edit files repeatedly, without manually having to unlock them every time.
This is especially important when users are not masters of the command line.
The [[direct_mode]] was made all files be unlocked all the time, but it
had many problems of its own.
## enter v6 mode
This led to the v6 repository mode, which makes unlocked files remain
unlocked after they're committed, so you can keep changing them and committing
the changes whenever you'd like. It also lets you use more normal git commands
(or even interfaces on top of git) for handling annexed files.

Unlocked files are handy, but they have one significant disadvantage
compared with locked files: They use more disk space.
While only one copy of a locked file has to be stored, normally,
While only one copy of a locked file has to be stored, often
two copies of an unlocked file are stored on disk. One copy is in
the git work tree, where you can use and modify it,
and the other is stashed away in `.git/annex/objects` (see [[internals]]).
The reason for that second copy is to preserve the old version of the file,
if you modify the unlocked file in the work tree. Being able to access
old versions of files is an important part of git after all.

That's a good safe default. But there are ways to use git-annex that
make the second copy not be worth keeping:
