Hi caevv,  
HiveMQ always persists its data.  
You can change the folder by following [the user guide](https://www.hivemq.com/docs/4.1/hivemq/configuration.html#folders).

Kind regards,  
Florian

So basically for the persistence storage folder, would it be?

`hivemq.data.folder` `HIVEMQ_DATA_FOLDER` `HiveMQ data folder`

In order to set your data folder you need to add the following:

As Java option:

`JAVA_OPTS="$JAVA_OPTS -Dhivemq.data.folder=/path/to/folder"`

as Environment variable:

`export HIVEMQ_DATA_FOLDER=/path/to/your/folder`

Please not that HiveMQ uses the HIVEMQ\_HOME/data folder by default, if you do not specifically set a folder.

First i use mqtt.fx gui client,it can’t receive offline message,  
then i use eclipse paho client,it can receive message,so it’s probably the mqtt.fx problem

Hi @hellomqtt,

Welcome to the forum.  
It’s possible that MQTT.fx has an issue here. HiveMQ CE does certainly queue offline messages for persistent (cleanStart=false / cleanSession=false )  
Have you tried the [MQTT CLI](https://hivemq.github.io/mqtt-cli/docs/quick_start.html) for testing, yet?

Best,  
Florian from The HiveMQ Team.
