Simple plugin that checks your WordPress install and shows your file permissions, size, and last modified date.
As of April 2026, File Permissions & Size Check is a WordPress file plugin with 300 active installations and a 4.8/5 rating from 4 reviews. It has been downloaded 21K+ times in total. Requires WordPress 2.8+ and PHP false+. Available on WordPress.org since 2011. Last updated 13 years ago — may have compatibility concerns. Top alternative: Theme Editor.
Will add a little “x” next to any files/folders set to 777, since this is inherently insecure. Checks all recursive folders that come with a default WordPress install.
This plugin can be CPU intensive as it iterates over your whole folder/file structure to gather statistics.
Notes :
This plugin will not return accurate results under IIS or WAMP stack due to how windows handles file permissions.
