Storing .accdb file on SD card

Hi can i store a .accdb file on the SD card? or should i convert it into .csv file? TY

A file is a collection of bytes, regardless of the extension. You can store any kind of file on the SD card.

Of course, you may run into problems with extensions with more than three letters, depending on which library you use.

What are you going to do with that file, after you get it written?
