Making a file read-only is a crucial method to ensure that your files are not accidentally modified or deleted. Read-only mode also helps in maintaining the integrity of the file by preventing unintended changes. This article will guide you through the steps to make a file read-only in various operating systems, including Windows, macOS, and Linux.
Methods to Make a File Read-Only

Windows
Using File Properties
Follow these steps to make a file read-only in Windows:

- Select ‘Properties’ from the context menu.
- In the ‘General’ tab, locate the ‘Attributes’ section.
- Check the ‘Read-only’ checkbox.
- Click ‘Apply’ and then ‘OK’ to save the changes.
The file is now set to read-only, and any attempt to modify it will be restricted unless the read-only attribute is removed.
Using Command Prompt
You can also make a file read-only using Command Prompt:
- Open Command Prompt as an administrator.
