## 19. How do I query the disk space occupied by data?
By default, TDengine data files are stored in /var/lib/taos and log files are stored in /var/log/taos.
To check the size of all data files, run the following command: `du -sh /var/lib/taos/vnode --exclude='wal'` .The wal directory is excluded here because the size is almost fixed in the case of continuous heavy writes, and wal directories are emptied whenever TDengine is normally shut down.
To check the size of all data files, run command `du -sh /var/lib/taos/vnode --exclude='wal'` on Linux Shell. The wal directory is excluded here because the size is almost fixed in case of continuous heavy writes, and wal directories are emptied whenever TDengine is normally shut down.
To check the size of a single database, run the `show vgroups;` command in the taos command to specify a database, go to /var/lib/taos/vnode with the obtained VGroup ID to check the contained folder size.
If you only want to see the block distribution and size of a (super) table, You can use _block_dist functions:
```mysql
SELECT _block_dist () the FROM {tb_name | stb_name}
