By default WordPress doesn't overwrite an existing file if you upload a new one with the same name and directory. Instead, it appends a number to the end of the filename in order to make it unique, e.g., filename1.jpg.
That isn't always the desired behavior, so this plugin makes it so that any files uploaded will automatically overwrite existing files, rather than creating a second file with a unique name.
UPDATE: This plugin no longer requires modifying WordPress Core. You can install it and it'll work automatically, without any other changes.
For help installing this (or any other) WordPress plugin, please read the Managing Plugins article on the Codex.
Once the plugin is installed and activated, it will start to work automatically.
Why do I see multiple copies of the file in the Media Library
WordPress allows files to have the same name if they're not in the same directory. So,
wp-content/uploads/2013/11/pizza.jpg can live alongside
wp-content/uploads/2013/12/pizza.jpg. This plugin only deletes existing files if they are in the same folder that the new file will be placed in.
Can I make a donation to support the plugin?
I do this as a way to give back to the WordPress community, so I don't want to take any donations, but if you'd like to give something I'd encourage you to make a microloan with Kiva.
Do you support this plugin?
I'm happy to fix reproducable bugs, but I don't have time to help you customize the plugin to fit your specific needs.
