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., <code>filename.jpg</code> becomes <code>filename1.jpg</code>.
That isn’t always the desired behavior, so this plugin makes it so that any files uploaded will automatically overwrite existing files in the same folder, rather than creating a second file with a unique name. It will not overwrite files in other folders.
After activating the plugin, you won’t need to do anything else, it’ll start working automatically. If you run into problems, please check the FAQ and existing support forum posts before opening a new support request.

Overwrite Uploads

Overwrites files with the same name and folder when uploading, instead of storing multiple copies with unique filenames.

Often times you use custom post types as bits of content but don’t want people to view them individually, outside their context, or search for them. This plugin does just that, allowing you to choose to redirect people to a different page, and even overwrite search results, on a granular, per-post basis.
This is useful, for example, if you have Staff as your custom post type, for example, but don’t want anyone visiting the single of that staff and instead want them going to a staff overview page.
Three options: 
1. Checking “Prevent” next to a custom post type will not allow any single views of that type, and will redirect viewers to another page of your site. 
2. Selecting the redirect page will redirect viewers of that single to this page – by default they will be redirected home. 
3. Selecting a search overwrite page will replace that custom post type’s results on the search page with your desired page; it will overwrite the permalink and the excerpt.
