About this app
Android app to format SD cards connected via USB OTG to FAT or FAT32.
How it works Detects USB mass storage devices via the USB Host API and lists them. When you select a device and filesystem type, the app attempts to format it using one of two methods:
Root path — runs mkfs.vfat -F 16/32 via su for full control over the filesystem type. Non-root path — uses StorageVolume.format() (API 24+) which formats the volume to the system default filesystem. Root is strongly recommended for reliable FAT/FAT32 formatting.
