+Payload:
+
+     Bytes | Content
+    -------|--------------------
+         n | Path
+         1 | 0x00
+
+Then, read type 0 for confirmation.
+Then, sendClose() (0xa response: 5x 00).
+
+If Path is a folder, it will be deleted together with its contents.
+
+

+The host will create a new folder in the given path, together with a
+matching .info file.
+The folder name cannot be chosen, and will be something like "Unnamed1".
+
+To create a folder with a specific name, use 0x66.
+Note that 0x66'ing a folder does not seem to set its time.
