File Permissions 038 Size Check is a free WordPress plugin designed to improve the security of your website by checking file permissions. This tool focuses on identifying files and folders set to insecure permissions, particularly those marked as 777, which can pose a risk to your site's integrity. It thoroughly scans the default WordPress installation, including root, wp-admin, wp-content, and wp-includes directories, as well as all associated subfolders, providing a comprehensive overview of your file permissions.

This plugin is particularly useful for developers and site administrators who want to ensure their WordPress environment is secure. It efficiently gathers statistics about file permissions while excluding certain file types, such as images and CSS, to streamline the process. However, users should note that the plugin can be CPU intensive, and it is recommended to run it during periods of low traffic. Additionally, it may not provide accurate results on IIS or WAMP stacks due to differences in how Windows manages file permissions.
