+### Please describe the problem.
+
+"directory" special remote leaves empty directories after dropping files. I
+compared it to rsync, and he cleans empty dirs, so I wonder if this is a bug in
+"directory".
+
+Also I think is it possible to make `testremote` also test for it? First I
+found this behavior in rclone special remote and was very confused, then
+compared to "directory" and got confused even more.
+
+### What steps will reproduce the problem?
+
+I made a little script :D, here it is:
+
+[[!format sh """
+#!/bin/bash
+
+test_dir=$(mktemp -d /tmp/test-empties.XXX)
+cd "$test_dir" || exit 1
+
+# create repo
+mkdir rep && cd rep || exit 1
+git init
+git annex init
+
+# add special remotes
+mkdir ../sp_directory
+git annex initremote sp_directory type=directory directory=../sp_directory encryption=none
+git annex initremote sp_rsync type=rsync rsyncurl=../sp_rsync encryption=none
+
+# add file and copy to remotes
+touch a
+git annex add a
+git commit -m commit
+git annex copy a --to sp_directory
+git annex copy a --to sp_rsync
+
+
+test_it() {
+    name="$1"
+
+    echo -e "\n\n"
+    echo "--------- special remote: $name ---------"
+    echo "--------- before drop: ---------" && tree "../sp_$name"
+    echo
+    git annex drop a --from "sp_$name" --force
+    echo
+    echo "--------- after drop: ---------" && tree "../sp_$name"
+}
+
+test_it directory
+test_it rsync

+### Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)

+I'm tinkering with annex for about 1 week, "doing research" in preparation to
+use it as storage for backups.
