   - Direct mode seems to work fine on the portable devices, but is now deprecated. It won't work on the V6 repositories.
 
-  - The new V6 repositories allows for the unlocking of files, replacing the link-like files (on Windows filesystems) with the real files, that allows me to browse them on the media player (by path and name). I did not find a way to keep them always unlocked by default, so I guess I would need to unlock them manually. Also, I would be keeping an extra copy of each file, since `annex.thing` won't work. In addition, as I don't expect to be editing any these files (not on these devices, at least), the loss of half the storage capacity is wasteful and undesirable.

   - Special remotes `directory` and `rsync` do not keep the original structure of the system, and for this reason do not fit for my purposes.

+I guess that fully getting rid of direct mode is a couple of years out.
+
+First, [[design/adjusted_branches]] needs to be implemented, to allow
+locked files to appear as unlocked automatically when a repository is
+checked out on a device that doesn't support symlinks.
+
+Then, a git-annex version with good enough support for v6 unlocked files
+needs to have been around long enough that basically everyone has upgraded.
+So in various stable and long term support version of linux distros, etc.
+Only at that point could direct mode repositories be automatically updated
+to v6 repositories.
+
+And yeah, it's potentially a problem that annex.thin doesn't work on
+Windows or FAT, and so converting such a repository doubles the disk use.
+I've added a note to [[todo/smudge]] to remember this is a potential thing
+to be improved before getting rid of direct mode. I think there are a
+couple of approaches that could avoid the problem.
+
+So, I recommend not being put off from using direct mode today out of
+worries that it might be removed 3 years from now.
+
+(You mentioned repeatedly unlocking. You shouldn't need to do that.
+In a V6 repository, when you unlock a file, that changes how it's
+represented in the git repository, so you can commit that change and it
+will be unlocked in other clones too. And if you `git add` large files,
+they'll be unlocked by default and you don't need to unlock them.)
