delete from device

Simple question (I tried using the search facility but it came up with nothing).

When using Calibre to delete a book from my (android tablet) device, and it is the last book from a particular author, do I have the option of choosing to keep the empty folder to use later?

I ask because I regularly delete read books from the tablet, but then a week or three later want to download another by the same author to the tablet - it's very annoying finding the folder gone and having to recreate it.

I've trawled the options in calibre itself but if there is this option I must have missed it - help anyone??
