UltraISO Premium Edition
Version 9.7.6.3860 · EZB Systems · Windows XP / 7 / 8 / 10 / 11 (32-bit and 64-bit) · ranked #235 in the library
The small utility that opens, edits and writes disc images without extracting them first, still the quickest way to pull one file out of a nine gigabyte image or turn one into a bootable stick.

About this release
Overview
UltraISO edits disc images in place. Open an ISO, add a file, delete a folder, rename something, and save. No extraction to a temporary folder and no rebuilding from scratch, which on a large image is the difference between ten seconds and twenty minutes. It reads and writes roughly thirty image formats and converts freely between them, so an image in one proprietary format becomes a standard ISO in one operation.
Bootable media is the other half of the job. It preserves boot information when editing an image so an installer image survives modification, extracts and injects boot sectors, and writes an image directly to a USB stick with the boot mode chosen explicitly. That last part is why it stayed in circulation long after the disc drive disappeared from most machines.
The rest is what you would expect from a mature small utility: create an image from files on disk or from a physical disc, mount an image to a virtual drive so its contents appear as a mounted volume, verify an image against its checksum, and drive the whole thing from a command line for scripted work. The interface is a two pane file manager and it has not needed to change in years.
What it does
Feature breakdown
In-place image editing
Add, remove and rename files inside an image and save without extracting and rebuilding, which on multi-gigabyte images saves a great deal of time.
Broad format support and conversion
Reads around thirty image formats including the proprietary ones from other burning applications, and converts any of them to standard ISO.
Bootable media creation
Write an image to a USB stick with an explicit boot mode choice, and extract or inject boot sectors when building custom installer media.
Image creation from disc or files
Build an image from a folder tree or read one from a physical disc, with the file system type and volume label set explicitly.
Virtual drive mounting
Mount an image to a virtual optical drive so an installer or a game runs from it without writing anything to physical media.
Command line interface
Every core operation available from the command line for scripted image building and batch conversion.
Changed in this build
Version 9.7.6.3860
- Improved handling of images larger than four gigabytes on FAT formatted destinations.
- USB write mode selection reworked with clearer options for legacy and UEFI booting.
- Support added for a further set of image formats produced by recent burning applications.
- Fixed a case where boot information was lost when saving a heavily modified installer image.
- Updated interface translations across several languages.
Installation
Follow these in order
- Extract the archive to a folder.
- Run the installer and pick the file associations you want.
- Apply the included licence details when the registration dialogue appears.
- Start the program and confirm the trial size limit is gone by opening a large image.
- Install the virtual drive component only if you want image mounting.
- Nothing else is required and it does not run in the background.
Release notes
From whoever packed it
- Writing to a USB stick erases it completely. Confirm the target drive letter before starting.
- For installer images that must boot on modern firmware, choose the UEFI compatible write mode rather than the legacy one.
- The virtual drive component installs a driver. Skip it if you only need to edit images.

Questions about this release
Answered before you ask
- Can it edit a bootable installer image without breaking it?
- Yes, boot information is preserved through edits, which is one of the main reasons people use it.
- Does it still burn to physical discs?
- Yes, if the machine has a drive. USB writing is what most people use it for now.
- Is there a file size limit in the trial?
- Yes, and applying the included licence removes it.
