diskfmt

What it does

• Small, easy defaults aimed at people coming from Windows.
• Filters out non-removable devices to avoid accidents.
• Defaults to GPT tables (you can switch to MBR in the UI).
• Creates a partition before formatting and prefers exFAT when available.

Download

Grab the AppImage build (requires UDisks2/Polkit on the host):

How to use it

Start the GUI with no arguments or with --start-ui. Common CLI flows:

• List removable devices: diskfmt list
• Format a device: diskfmt format --path /dev/sdb1 --fs vfat --label USB --quick
• Pick a filesystem block size or table type with --size and --table.

Install exfatprogs if you need exFAT support on your distribution.

Building

Requires Rust, a C++17 compiler, and common FLTK/X11 build dependencies (libx11-dev, libxft-dev, libxrender-dev, etc.). Build a release binary with:

cargo build --release

Use --features fltk/use-wayland to build with hybrid/X11 support or --no-default-features for a CLI-only build.
