WordPress upload file names can be quite predictable sometimes, especially if uploading from the same camera – DKIM1004 comes after DKIM1003. If not all of the content on your site is public, this can be a problem as people can snoop on your media folder by guessing file names.
This plugin prepends a short 8 character hash to the beginning of every uploaded file. For example, DKIM1004.jpg turns into 8df8078e-DKIM1004.jpg. The hash is not cryptographically secure and just makes it a bit more difficult to guess file names.
The plugin works on all upload file types and all sizes of a given image get the same prefix.

Media File Name Guess Preventer

Prepend a random string to media file uploads to prevent file name guessing.

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.
