Neostore. * file size after removing millions of node

Question

I use neo4j 1.9.4, I store 28M nodes, 267M properties and 157M relationships.

neostore files. *:

-rw-r - r-- 1 user wheel 10961964959 7 fév 09:58 neostore.propertystore.db
-rw-r - r-- 1 user wheel 5185764606 7 fév 09:58 neostore.relationshipstore.db
-rw-r - r - 1 user wheel 3550760192 7 fév 09:58 neostore.propertystore.db.strings
-rw-r - r-- 1 user wheel 249658236 7 fév 09:58 neostore.nodestore.db

I am removing 26M nodes and neostore. * does not decrease:

-rw-r - r-- 1 user wheel 10961964979 7 fév 10:20 neostore.propertystore.db
-rw-r - r-- 1 user wheel 5185764630 7 fév 10:20 neostore.relationshipstore.db
-rw-r - r - 1 user wheel 3550760218 7 fév 10:20 neostore.propertystore.db.strings
-rw-r - r-- 1 user wheel 249658252 7 fév 10:20 neostore.nodestore.db

i removes all nodes from the ticket index, the lucene index / index / lucene / node / ticket folder is empty when I count all the ticket nodes, I get 0 → OK

why the file size is neostore. * not decreasing?

here delete code =

EndResult<Ticket> tickets = ticketRepository.findByDate(date); // by 1000
Iterator<Ticket> itTicket = tickets.iterator(); 

  while (itTicket.hasNext()) { 

 Ticket t = itTicket.next(); 
 Node n = neo4jTemplate.getGraphDatabase().getNodeById(t.getId()); 
 neo4jTemplate.getIndex("Ticket").remove(n); 

 Iterable<Relationship> relationships = n.getRelationships(); 

  for (Relationship relationship : relationships) { 

    relationship.delete(); 
 }
 n.delete(); 

 }
