I did a merge between the trunk and a branch.
On the trunk, there is a folder, let\'s say templates/Toto.
On the branch, everything but the folder Toto is there
If the following doesn't work (it didn't for me), try it through the IDE. I tried it through Netbeans and it worked.
First select the directory and resolve conflicts. It automatically asks whether you want to accept your working directory structure.
svn resolve --accept working templates/Toto
