Datafile storage location changing or defining in any CREATE situation

Hi, coming from ORACLE experiences i am used to define, where all the files sit in the host os. We now run MariaDB 10 on Synology DSM.

I do not find any obvious way to asign e.g. a new database to go to a specific folder or e.g. a folder defined by a file share. where do i find that options e.g. in DDL or is it simply just not existing.

all files reside on VOLUME Level where the e.g. cannot accessed with DSM Utilities as they basically adress activities only on file-share level.

thx
