+# Create A New File In A New Directory
+
+From within a vim session, if you create a buffer for a new file in a
+directory that doesn't exist. For instance, let's say that `/features`
+doesn't exist and the new file is `my_latest_feature_spec.rb`:
+
+```
+:e spec/features/my_latest_feature_spec.rb
+```
+
+Vim's command line will inform you that this is a buffer for a `[New
+DIRECTORY]`. If you then make some changes and subsequently try to save the
+file, Vim will present you with:
+
+```
+"spec/features/my_latest_feature_spec.rb" E212: Can't open file for writing
+```
+
+This is because the containing directory doesn't exist. You can quickly
+create that directory with a combination of Vim filename shorthands and
+shelling out to the `mkdir` command.
+
+```
+:!mkdir -p %:h
+```
+
+The `%` is shorthand for the qualified path of the current file. The `:h` is
+a filename modifier that returns the *head of the filename*, that is, it
+resolves to the path with everything except the name of the file.
+
+Thus, this command is essentially resolving to:
+
+```
+:!mkdir -p spec/features/
+```
+
+Vim will shell out with this command making directories for all non-existent
+directories in the given path. Now you can happily save your new file.
