How can I find out what format my microSD card in S9 has? Is there an app for this?

I have a Samung S9+ phone running Android 10. How can I figure out if the microSD card that I inserted is ext3 or fat32 or whatever? Is there an app for that?

It should say on the sd card or package?

Was this brand new or from another device?

mustang, not sure if looking at the card or the package would help. it was brand new at some time.
Anyway, I downloaded some apps which told me that the filesystem of the microsd card is sdcardfs.
