Chromebooks have become increasingly popular due to their simplicity, affordability, and excellent security features. However, sometimes you may need to work with files in a specific format, like a ROM file, which requires unzipping before you can use them. This guide will walk you through the process of unzipping a ROM file on your Chromebook, making it accessible for all your needs.
Understanding ROM Files and Unzipping
ROM files, or Read Only Memory files, are compressed archives that often contain a collection of files. These files are commonly used for game emulators, operating systems, and other software distributions. To use the files inside a ROM, you need to unzip it, which essentially extracts all the files from the archive.
Unzipping with Online Tools
1. Google Drive
Google Drive is a versatile online platform that includes a built-in file extractor. This makes it a convenient option for unzipping ROM files on your Chromebook:
- Upload the ROM file to your Google Drive: Navigate to your Google Drive, click on “New,” and choose “File upload.” Select your ROM file from your Chromebook’s storage.
- Right-click on the ROM file: A menu will appear. Look for the “Extract” option.
- Choose a destination folder: You can select the default folder or choose a different location on your Google Drive.
- Extract the files: The process will automatically extract the files from the ROM, creating a new folder containing the extracted files.
2. Online Unzipping Services
Several online unzipping services are available, allowing you to extract files directly from your browser without downloading any software. Some popular options include:
- Online-Convert: This service supports a wide range of file formats, including ROM files. You can upload your ROM file, select the extraction option, and download the extracted files directly to your Chromebook.
- B1 Online Archiver: Another comprehensive option, B1 Online Archiver allows you to extract files from various archive formats, including ROM files. You can upload your file and choose a destination folder on your Google Drive to store the extracted files.
Unzipping with Linux (Crostini)
Chromebooks running Chrome OS 69 and above offer a feature called Crostini, which allows you to run Linux apps alongside your Android apps. This opens up a world of possibilities, including using command-line tools to unzip ROM files:
1. Enable Crostini
If you haven’t already, enable Crostini on your Chromebook. You can do this by:
- Opening Settings: Go to the bottom right corner of your Chromebook screen and click on the “Settings” icon (a gear).
- Navigating to “Linux apps”: Under “Advanced,” select “Linux apps.”
- Turning on “Enable Linux apps”: Click on the toggle switch to turn on Linux apps.
- Selecting a username: You will be prompted to choose a username for your Linux instance.
2. Install Unzip Tool
Once Crostini is enabled, you can install the ‘unzip’ tool:
- Open the Linux terminal: Click on the “Linux apps” icon on the bottom shelf of your Chromebook.
- Type the following command and press Enter:
sudo apt-get update && sudo apt-get install unzip
This will install the ‘unzip’ tool to your Linux environment.
3. Unzip the ROM File
You can now use the ‘unzip’ command to extract the files from your ROM:
- Locate your ROM file: Determine the path to your ROM file on your Chromebook. You can use the file manager to locate it.
- Open the Linux terminal: As before, open the Linux terminal by clicking on the “Linux apps” icon.
- Enter the following command: Replace
[ROM file path]with the actual path to your ROM file.
unzip [ROM file path]
This will extract all the files from the ROM into the current directory of the terminal.
4. Accessing the Extracted Files
The extracted files will be located within the directory where you ran the ‘unzip’ command. You can navigate through the Linux file system to access them or copy them to a different location on your Chromebook.
Unzipping with Android Apps
Android apps can also be used to unzip ROM files on your Chromebook. While Android apps are not as powerful as command-line tools, they offer a user-friendly interface for extracting files:
1. Install a File Manager App
The Google Play Store offers numerous file manager apps that support unzipping. Some popular options include:
- Files by Google: A lightweight and reliable file manager app developed by Google.
- Solid Explorer: A feature-rich file manager that includes a built-in zip/unzip functionality.
2. Locate the ROM File
Use your chosen file manager app to find the ROM file on your Chromebook’s storage.
3. Extract the Files
Most file manager apps include a built-in option to extract zipped files. Simply locate the ROM file, long-press it, and select the “Extract” option. Choose a destination folder for the extracted files and proceed with the extraction process.
Tips for Unzipping ROM Files
- File Size: If the ROM file is large, it may take some time to unzip. Be patient and ensure you have enough storage space available on your Chromebook.
- File Type Compatibility: Most unzipping tools support a wide range of archive formats. However, ensure your chosen method supports the specific type of ROM file you’re working with.
- Security: Download ROM files only from trusted sources to avoid downloading malicious files.
Conclusion
Unzipping a ROM file on your Chromebook is a straightforward process that can be accomplished using several methods. Whether you prefer online tools, the command-line with Crostini, or dedicated Android apps, you’re well-equipped to access the contents of your ROM files and utilize them for your desired purpose. Remember to always prioritize security by downloading files only from reliable sources and using reputable unzipping tools.
Frequently Asked Questions
What is a ROM and why would I need to unzip it on my Chromebook?
A ROM, or Read-Only Memory, is a file containing the operating system and other essential data for your Chromebook. Unzipping a ROM is often necessary when you want to install a custom operating system or update your current one. This might be done to access newer features, fix bugs, or even install a different operating system altogether. It’s essential to understand that modifying your Chromebook’s ROM can potentially void your warranty and requires advanced technical knowledge.

Is it safe to unzip a ROM on my Chromebook?
Unzipping a ROM itself isn’t inherently dangerous, but it’s crucial to be cautious. Ensure the ROM you are unzipping is from a trusted source to prevent malware or corrupted files from compromising your device. Always back up your Chromebook’s data before attempting any system modifications, as improper handling can lead to data loss or potential issues.
What happens after I unzip the ROM?
Once you unzip the ROM, you will gain access to its contents, including the operating system files and other necessary components. These files are typically in a specific format that requires special tools to be installed on your Chromebook. You can then use these files to flash your Chromebook with the new operating system or update the existing one, depending on your purpose.

The wrong ROM could cause serious issues with your Chromebook, including rendering it unusable. Always make sure you are using the correct ROM for your device before attempting to unzip it.
What should I do if I encounter errors while unzipping the ROM?
If you encounter errors while unzipping the ROM, it could be due to various factors like a corrupted file, insufficient storage space, or incompatibility issues. First, try restarting your Chromebook and the unzipping tool. If the problem persists, check the integrity of the ROM file you are trying to unzip. If the file is corrupted, you may need to download a fresh copy from a reliable source.
