However, to access the documents it contains, you first need to unzip it. Many users wonder how to open a ZIP file on Windows, Mac, or smartphone. In this comprehensive article, you will learn how to easily unzip a ZIP file, step by step, regardless of your device.

What is a ZIP file?
A ZIP file is a compressed folder. It contains one or more files that have been reduced in size. This compression simplifies sharing, as it decreases the overall weight of the documents.
Companies often use ZIP archives to send multiple files in a single attachment. Individuals also use them to back up photos, videos, or important documents.
However, you cannot directly modify a file contained in a ZIP archive. You must first extract the files. This action is also known as decompression.
Why decompress a ZIP file?
You need to decompress a ZIP file to access its content. Without this step, you cannot properly open or modify the files it contains.
Decompression has several advantages:
- It restores files to their original format.
- It allows for editing and saving documents.
- It facilitates organization within your folders.
- It avoids reading errors related to compression.
Thus, if you receive a compressed folder by email, you need to extract it before use.
How to decompress a ZIP file on Windows
Windows has a built-in tool to open a ZIP file. Therefore, you do not need to install additional software unless you want advanced features.
Simple method with File Explorer
Follow these steps to decompress a ZIP file on Windows:
- Locate the ZIP file on your computer.
- Right-click on the file.
- Select "Extract All".
- Choose the destination location.
- Click "Extract".
Windows then creates a new folder containing all the extracted files. You can use them immediately.
Using software like WinRAR or 7-Zip
You can also use specialized software, as it offers more options. 7-Zip and WinRAR are among the most popular solutions.
With 7-Zip, proceed as follows:

These tools also handle other formats like RAR or TAR, which can be useful if you frequently work with archives.
How to decompress a ZIP file on Mac
MacOS also offers a built-in solution. The system uses the Archive Utility to automatically extract files.
Quick decompression on Mac
To open a ZIP file on Mac:
- Locate the ZIP file in Finder.
- Double-click on the file.
The Mac will immediately create a folder in the same location. This folder contains all the decompressed items.
If the decompression fails, check the permissions or re-download the file, as it may be corrupted.
Using a third-party application
Some applications like The Unarchiver offer more options. They support more formats. You can download them from the App Store.
How to decompress a ZIP file on Android
Android smartphones also allow you to open ZIP files. Most devices include a file manager capable of extracting archives.
Steps to follow on Android
- Open the "Files" app.
- Locate the downloaded ZIP file.
- Tap on it.
- Select "Extract".
Your phone will then create a folder with the decompressed files. You can then open them normally.
If your device does not offer this feature, install an app like WinZip or RAR from the Google Play Store.

The iPhone will automatically create a folder containing the extracted files.
If you are using an older version of iOS, a third-party application may be necessary.
Troubleshooting issues during decompression
Sometimes, decompressing a ZIP file may fail. Several causes can explain this problem.
Corrupted ZIP file
An incomplete download can damage the archive. In this case, download the file again, as the current version may be unusable.
Password required
Some ZIP files are password protected. You must enter the correct password before extracting the files.
Insufficient storage space
Check the available space on your device. Decompression requires enough free memory, especially if the archive contains large files.

|---|---|---|
| Windows | Windows Explorer | 7-Zip, WinRAR |

Best practices after decompressing a ZIP file
After extraction, organize your files clearly. Move them into the appropriate folder, as this makes future reference easier.
Delete the ZIP file if you are short on disk space. However, keep it if you wish to retain a compressed copy.
Also, scan the files with antivirus software, especially if you downloaded the archive from the Internet. This precaution reduces the risk of malware.
