YUMI exFAT 1.0.3.5

Drop a Comment

YUMI (Your Universal Multiboot Installer) exFAT lets you load multiple operating systems, antivirus rescue discs, diagnostic tools, and recovery utilities onto a single USB drive - all without terminal commands or complex partitioning.

The exFAT formatting removes the 4 GB file size barrier that blocks modern Windows installers and larger Linux distributions on standard FAT32 drives.

What Sets YUMI exFAT Apart

The exFAT version solves a specific problem: Windows 11 ISOs and many current Linux distributions exceed 4 GB, making standard FAT32-based tools unusable.

YUMI exFAT handles these oversized images natively while maintaining full BIOS and UEFI compatibility.

If you only work with smaller ISOs or need a single-boot drive, Rufus remains the fastest option for straightforward USB creation.

Persistence support lets you save files and settings in live Linux sessions - up to 40 GB on supported distributions.

This turns your USB drive into a portable workspace that travels between machines.

For users who prefer copying ISOs without running any installer at all, Ventoy takes a different approach by detecting ISOs dropped into its folder automatically.

Key Features

YUMI exFAT integrates the Ventoy bootloader for broad ISO compatibility, covering hundreds of Linux distributions, Windows installers from 7 through 11, and specialized rescue tools like Kaspersky Rescue Disk and Clonezilla for disk imaging.

Drag-and-drop convenience lets you place ISOs directly into the YUMI folder on your USB drive, and they appear in the boot menu without rerunning the application. Check our step-by-step guide on how to add multiple ISOs to one USB with YUMI exFAT for a detailed walkthrough.

The tool is free, open source, and portable - no installation required. All versions include full source code upon release.

When to Use YUMI exFAT vs Alternatives

Choose YUMI exFAT when you need multiple bootable ISOs on one drive and your images exceed 4 GB. For the standard YUMI Multiboot USB Creator on FAT32 drives with smaller ISOs, the classic version works fine.

Users installing Windows 11 on older hardware should pair their bootable USB with FlyOOBE to bypass TPM and CPU requirements.

For writing a single ISO to USB or SD card with built-in verification, balenaEtcher keeps things simple. And if you need to create a portable Windows installation that runs directly from an external drive, WinToUSB handles Windows To Go configurations.
