UltraISO Premium Edition

About UltraISO Premium Edition

The unusual thing about this tool is that it edits an image file in place. Most utilities can only build a new image or extract from an existing one, whereas here a file is added to or removed from an image directly and the result is saved without rebuilding the whole thing from a folder. On a multi-gigabyte installation image that is the difference between a minute and an afternoon.

Bootable media is the job it gets used for most. Writing a bootable image to a USB stick handles the boot sector correctly, offers the different write methods for machines that are picky about which one they accept, and works with both the older and newer firmware boot paths. It also extracts and preserves boot information from an existing bootable image so a modified copy still starts.

Format handling is broad. It reads the standard image format plus the proprietary formats several older burning suites produced, and converts between them, so an image from a decade old tool becomes something a current machine can mount. Compressed image formats are supported in both directions.

The rest is a mounting driver for opening an image as a virtual drive without writing anything, direct burning to optical media where a drive is still fitted, checksum verification after a write, and a file browser that treats an image like a folder tree for dragging things in and out.

What is included in this build

• Direct in-place editing of image files without rebuilding them
• Bootable USB creation with several write methods for awkward firmware
• Boot information extraction and preservation from existing bootable images
• Conversion between the standard image format and older proprietary formats
• Virtual drive mounting for opening an image without writing it out
• Direct burning to optical media with post-write verification
• Drag and drop file browser treating an image as a folder tree
• Compressed image support for reading and writing

Changed in version 9.7.6.3860

• Improved bootable write reliability on newer firmware implementations
• Support added for larger capacity USB media
• Faster handling of images above eight gigabytes
• Fixed a rare corruption when saving an edited image over itself
• Refreshed interface language files

Installation walkthrough

These steps assume a clean machine. If a previous release of the same application is present, deal with that first, since an overlapping install is the most common cause of a setup that stops halfway.

1. Extract the archive and run setup as administrator.
2. Allow the virtual drive component to install if image mounting will be used.
3. Reboot once so the virtual drive registers with the system.
4. Back up the source image before editing it in place, since the save overwrites.
5. Confirm the correct target device before writing to a USB stick, as writing erases it.
