How to decompress an iso file

ISO file is a common disc image file format, which is usually used to store the entire contents of a disc, including files and file systems. When we need to access the contents of the ISO file, we need to decompress it. This article will introduce several common methods to decompress ISO files.

1. Use virtual optical drive to decompress
   This is one of the most commonly used methods to decompress ISO files. First, we need to install a virtual optical drive software, such as DAEMON Tools Lite, PowerISO, etc. Then, double-click the virtual optical drive software icon and click "Add Image" or similar option in the software. Select the ISO file you want to unzip and load it into the virtual optical drive. At this time, the contents of the ISO file will appear on your computer like a real CD, and you can directly open the folder, copy files, and other operations.
2. Use decompression software to decompress
   If you only need to decompress some files in the ISO file or want to directly obtain the contents of the ISO file, you can use decompression software to decompress it. WinRAR, 7-Zip, PeaZip and other software all support decompressing ISO files. First, install and open the decompression software, then select File -> Open (or drag and drop directly to the software interface) to find the ISO file you want to decompress. Next, select extraction options, including extracting to a specified folder or extracting a specific file. Finally, click the Extract button and the software will decompress the ISO file.
3. Use the built-in function of the operating system to decompress
   Some operating systems have built-in functions to decompress ISO files, including Windows 10 and Mac OS. In Windows 10, you can directly double-click the ISO file, and the system will automatically mount it as a virtual optical drive and open the contents. You can also right-click the ISO file and select the "Mount" option in the pop-up menu. In Mac OS, you can double-click the ISO file and the system will automatically extract it to a new folder.

No matter which method is used to decompress the ISO file, we should pay attention to the following points:

• Make sure that the ISO file you download is safe and reliable. Avoid downloading ISO files from unknown sources or unverified websites to prevent security risks.
• Make sure you have enough hard disk space to store the decompressed files. ISO files often hold large amounts of data, so the decompressed files may take up a large amount of space.
• Password-protected ISO files need to be decompressed by entering the correct password before decompression. Make sure you know the password for the ISO file and enter it correctly when unzipping.

In short, decompressing an ISO file is a common operation and a necessary step to access the contents of the ISO file. By using a virtual optical drive, decompression software or the functions that come with the operating system, we can easily decompress the ISO file and obtain its contents. However, when unzipping ISO files, we should pay attention to security and storage space, and make sure we have the correct password (if required).
