+``files:repair-tree`` try and repair malformed filesystem tree structures.
+If for any reason the path of an entry in the filecache doesn't match with
+it's expected path, based on the path of it's parent node, you end up with an
+entry in the filecache that exists in different places based on how the entry
+is generated. For example, if while listing folder ``/foo`` it contains a file
+``bar.txt``, but when trying to do anything with ``/foo/bar.txt`` the file
+doesn't exists.
+
+This command attempts to repair such entries by querying for entries where the path
+doesn't match the expected path based on it's parent path and filename and resets it's
+path to the expected one.
