If, like me, privacy and data security are important to you in the modern digital age, then I will show you one interesting way to protect information - steganography, the art of hiding files inside images. Thanks to this method, you can transfer data secretly from strangers.

In this post, I will tell you how to quickly hide a file in an image using the built-in tools of the operating system, without the need to install additional programs. Whether you're a Windows or Linux user, this step-by-step guide will help you master this useful skill.

**Step 1: Create an archive**

1. Gather all the files you want to hide into one folder.
2. Create an archive from these files. Let the archive be called **files.zip**.

**For Windows:**

1. Select the files you want to add to the archive.
2. Right-click on the highlighted files.
3. Select "Send" -> "Compressed ZIP Folder".

**For Linux:**

1. Open a terminal and navigate to your files folder using the command **cd /path/to/folder**.
2. Use the **zip** command to create an archive: **zip -r files.zip**.

**Step 2: Hiding the archive in the image**

**For Windows:**

1. Prepare an image (eg **img.jpg**) and archive (eg **files.zip**).
2. Make sure both files are in the same folder.
3. Open a command prompt. To do this, press the key combination **Win + R**, type **cmd** and press **Enter**.
4. Go to the folder where the files are located. To do this, use the command **cd pathfolder**.
5. Use the **copy** command to merge files: **copy /b img.jpg + files.zip output.jpg**. Here **img.jpg** is your image, **files.zip** is the file archive you want to hide, and **output.jpg** is the name of the output image in which the archive will be hidden. Now the **files.zip** archive is hidden inside **output.jpg**.

**For Linux:**

1. Prepare an image (eg **img.jpg**) and archive (eg **files.zip**).
2. Make sure both files are in the same folder.
3. Open a terminal.
4. Navigate to the folder where the files are located using the command **cd /path/to/folder**.
5. Use the **cat** command to merge files: **cat img.jpg files.zip > output.jpg**. Here **img.jpg** is your image, **files.zip** is the file archive you want to hide, and **output.jpg** is the name of the output image in which the archive will be hidden. Now the **files.zip** archive is hidden inside **output.jpg**.

**Extracting a hidden archive**

**For Windows:**

1. Open a command prompt and navigate to the image folder using the **cd pathtofolder** command.
2. Rename the file **output.jpg** to **output.zip**.
3. Open the archive using any archiver.

**For Linux:**

1. Open a terminal and navigate to the image folder using the command **cd /path/to/folder**.
2. Use the **tail** command to extract a hidden archive: **tail -c +$(( $(stat -c %s img.jpg) + 1)) output.jpg > extracted_files.zip**.
3. Open the **extracted_files.zip** file using any archiver (for example, **unzip**).

Now you know how to hide an archive with files in an image without using third-party utilities. This method is simple and does not require additional software, but keep in mind that advanced steganography may require specialized tools.
