How can I check if the data or file is encrypted or not?

[Sungwoo]

There is storage that is using NVE.
The command can confirm whether the volume is encrypted.
By the way, is there a way to check if the data or files in the volume are encrypted?

Interesting query. According to this detailed KB - Encryption happens at the RAID layer, which is way below the file-system(files)/protocol(cifs/nfs/iscsi)/application layer. After a read operation, data is unencrypted when the data leaves the RAID layer.

You can’t 

you can check if the vol is and then believe all it’s contents are

Pedro is correct here, NVE is basically protecting your data from being read from a drive that has been removed from the system.
