Hello Mister Bambu Lab: how can one delete Files on the A1 micro SD?

Bambu Lab A1 Series Bambu Lab A1 mini

On the X1C one can delete File by File on the Micro SD. Not so on the A1 mini. No delete.

Hello Mister Bambu Lab, make a firmware update please, for deleting file by file.
Thanks a lot in advance.
Roscano.

Sorry for asking twice
