There are two things that make storage not free up.
1. The file has hardlinks. You can tell by looking at ls -l
-rw-r--r--  1 steveo steveo   56 Apr  9 15:06 doc.txt

The "1" means that only one name points to those blocks of storage.

2. If multiple channels are open on a file and the file is deleted then 
the storage won't free up till the last channel on that file is closed.

Link count or open count.
