Part4: ISO & IMG Files: What Are the Differences?

Differences Between ISO and IMG Formats:


ISO File

IMG File

File Origin

Typically associated with optical discs (CDs, DVDs).

Versatile and can represent various disk images, including hard drive backups and raw data.

Common Usage

Often used for distributing software, operating systems, and disc images.

Used for various disk image tasks, including backups and virtual machine storage.


Generally compatible with most disc burning and mounting software.

Compatible with a wide range of applications but may require format conversion in some cases.

Mounting and burning

Easily mounted or burned using standard software tools.

Can often be treated like ISO files for mounting and burning purposes.

Specialized Use Cases

Primarily for optical disc emulation.

Suitable for a broader range of tasks, including hard drive backups and data storage.


  1. File Conversion: If you have an IMG file and need to use it as an ISO, consider using conversion tools to change the format if necessary.

  2. Mounting and Burning: For practical purposes, many software tools treat IMG files like ISO files, so try mounting or burning the IMG as if it were an ISO if needed.

  3. Data Backup: IMG files can be useful for creating backups of entire drives, so consider this when choosing a format for your backup needs.


1. Are ISO files available for all Office 2021 editions?

Microsoft typically provides ISO files for various editions of its Office suites, including Office 2021. You should be able to find ISO files for editions such as Home & Student, Home & Business, and Professional Plus. However, the availability of specific editions and the download methods may vary, so it's advisable to visit the official Microsoft website or trusted sources for the most up-to-date information and downloads.

2. Can I use the same ISO file for multiple installations?

Yes, you can use the same ISO file for multiple installations of a software application, including Microsoft Office 2021, as long as you have valid and unique product keys for each installation. Each product key is associated with a separate license, allowing you to install and activate the software on multiple devices or for multiple users, depending on the terms and conditions of the software's licensing agreement. Always ensure that you are using genuine product keys and complying with the software's licensing terms to avoid any legal or activation issues.

3. Do I need to back up my data before installing Office 2021 from an ISO file?

Yes, it's advisable to back up your important data before installing Office 2021 from an ISO file or performing any software installation. This precautionary step helps prevent data loss in case anything goes wrong during the installation process, ensuring that your valuable files and documents are safe and can be restored if needed.
