The disk image term refers to many data storage mediums such as optical disk, hard drive, USB flash drive, tape drive or even floppy disk. Their creation process comprises a 100% sector-by-sector copy of the source resulting in a complete replication of both content and structure. The file formats of disk images are as popular as standard image formats within specific communities.
As every particular file format has its own category of dedicated software, so disk images have their tools that can be used to efficiently manage them. Top picks include PowerISO, CloneCD, IsoBuster, Blindwrite, MagicISO Maker, WinImage or WinISO. Beside these particular software, many users prefer UltraISO for a number of reasons. Some of them because of its longevity and the fact that they got used to it, others tend to perpetually search for feature-rich, easy-to-use and powerful software.
One of the main features of UltraISO is the vast array of disk image file formats it supports. This consists of mainstream formats such as ISO, BIN, CUE, MDS, MDF, NRG, CCD, IMG, UIF or VCD as well as less popular formats like ASHDISC, BWT, BWI, DAA, DMG, HFS, IMA or C2D. In addition, the application supports many other types of disk images with a grand total of over forty formats. Moreover, the software can easily convert between any of the aforementioned file types.
UltraISO provides a classic and neat interface that holds all the tools for creation, editing, extraction of disk image content as well as management of its structure. The `New` sub-menu of the `File` menu offers an impressive palette of options like `Data / Bootable CD / DVD Image`, `UDF / XBOX DVD Image`, `PS2 CD / DVD Image`, `Hybrid / Unix / Linux / Audio / Mixed Mode CD Image` or Floppy / Disk Image.
Another important menu of the application's main window is the `Tools` menu which holds a witty collection of tools to satisfy your conversion, mounting, burning, checking, verifying, compressing or testing needs. Bootable disk images have their own menu for all of your essential utilities such as `Make / Write Floppy / Disk Image` or `Make Multi-Boot CD/DVD`.
The comprehensive set of features alongside an enormous number of supported disk image file formats recommend UltraISO as a top player within the software industry. It is very well-built and its capabilities rise high above the average, delivering the best results for any disk image-related task at hand. Simply put, UltraISO does not take more than a few minutes to prove its reliability when it comes to creating and extracting disk image files as well as editing any aspect of their structure.
