What is Win32 Disk Imager (Portable)?

Win32 Disk Imager is a utility to write raw disk images (e.g., .img, .iso, .raw) to USB/SD drives, or back up drives to image files.
The portable version runs directly from a folder or USB stick without modifying the Windows registry or system.

Win32 Disk Imager Portable is a lightweight, open-source tool designed to write raw disk images (like .img or .iso) to removable storage devices like SD cards or USB flash drives. While the official SourceForge version is typically an installer, portable versions are available through platforms like Chocolatey or community-maintained packages on PortableApps.

• Raw image write: Writes a binary image file bit-for-bit to a target block device. Suitable for OS images (e.g., Raspberry Pi), embedded firmware, or duplicating entire removable drives.
• Raw image read: Reads a device to an image file to produce a backup copy of whatever is on the target media.
• Device selection: Straightforward pick-list of mounted removable devices.
• Progress indicator: Basic write/read progress bar and byte count.
• Portable footprint: No installer; the app can be carried on removable media.
• Low-level access: Works at block device level rather than cluttered partition-level logic—simpler but more powerful.

Benefit: A backup of a 4GB Raspberry Pi SD card (inside a 32GB card) creates a 4GB file, not a 32GB file.
