How to Open Ubuntu Files on Windows 11 and Access Ubuntu Files from Windows 11

Windows 11 cannot natively read ext4, the filesystem Ubuntu relies on. When you check Disk Management, the Linux partition appears as RAW or Unknown, with no drive letter assigned. File Explorer offers only one option — Format Disk — which would wipe all your Ubuntu data.

To bridge this gap, you need tools or workflows designed to safely access Linux partitions from Windows. Options like DiskInternals Linux Writer™ for full read/write access, Linux Reader™ for safe read‑only browsing, or WSL2 disk mounting for developer setups make it possible to open Ubuntu files directly in Windows without risking corruption.

This guide walks through the most reliable methods to access Ubuntu partitions from Windows 11, so you can manage files seamlessly across both operating systems.

3 Ways to Access Ubuntu Files from Windows 11

Method 1: DiskInternals Linux Writer™ — Read and Write Ubuntu Files from Windows 11 (Recommended)

Linux Writer™ opens Ubuntu’s ext4 partitions directly in Windows 11 — no driver installation, no terminal commands, no reboot. It uses original Linux driver components (Cygwin + e2fsprogs), so file integrity is preserved exactly as Linux would handle it. Works on internal dual‑boot partitions and external ext4 drives.

Features:

• Read and open Ubuntu files in Windows 11
• Write new files and edit existing ones
• Delete, rename, and create files/folders
• Access home directories, documents, configs without reboot

Steps:

1. 1. Download and install DiskInternals Linux Writer™
2. 2. Launch the application
3. 3. Select the Ubuntu (ext4) partition from the drive list
4. 4. Browse and manage files — interface works like Explorer
5. 5. Close the app cleanly before booting back into Ubuntu

Method 2: DiskInternals Linux Reader™ — Free Read‑Only Access to Ubuntu Files

Linux Reader™ provides free, read‑only access to Ubuntu’s ext4 partitions. No risk of accidental writes or corruption.

Features:

• Supports ext2, ext3, ext4, HFS/HFS+, ReiserFS, XFS, ZFS, UFS2, APFS, RAID arrays
• Bypasses Linux file permissions — all files visible
• Ideal for copying files off Ubuntu drives without modification

Method 3: WSL2 with wsl --mount — Terminal‑Based Ubuntu File Access

WSL2 runs a real Linux kernel inside Windows. With wsl --mount, you can attach physical disks and access ext4 partitions.

Requirements:

• Windows 11 with WSL2 enabled
• Virtualization on in UEFI
• Elevated PowerShell session

Steps:

# Identify the disk number
Get-Disk

# Mount the disk (replace 1 with your disk number)
wsl --mount \\.\PHYSICALDRIVE1

# Access via File Explorer
\\wsl$\\mnt\wsl\

# Unmount before shutdown
wsl --unmount \\.\PHYSICALDRIVE1

Limitations:

• Mounts whole disks only, not single partitions
• Cannot mount the disk holding Windows 11
• Requires admin access each time
• Must unmount before shutdown to avoid ext4 corruption

DiskInternals Linux Writer™: Open Ubuntu Files on Windows 11 Without Rebooting

Linux Writer™ is the most direct path to Ubuntu files on Windows 11. Install it once, select the Ubuntu partition, and access files exactly as you would in Windows Explorer — no commands, no dual‑boot switching, and no risk of Windows formatting the partition by mistake.
