Accidentally Deleted Dual Drive's application

Hi, i use a sandisk dual drive type-c usb. I just reformed it to NTFS format to transfer large files.

But it removed the app inside the usb witch provides to connect the usb to the mobile phone.
Now, my phone can not see the usb and usb is tottally empty. How can i fix it ? Also sorry for my grammer.

I would be very surprised if your phone can read a NTFS drive. To handle files larger than 4 GB use the exFAT format. The phone may be able to work with that.
