“Destination Folder Already Exists” is a common WordPress error that generally occurs during plugin or theme installation. WordPress shows this error message to prevent a destination folder with the same name and path from being overwritten. The article will highlight ways on how to fix the "installation failed: destination folder already exists" error in WordPress.

When a plugin or theme’s installation fails, it leaves behind an empty destination folder. The same happens when an old plugin or theme’s folder isn’t removed properly due to an interruption. This rogue folder stops WordPress from completing the installation.

What Is the Installation Failed: Destination Folder Already Exists Error?

Installation Failed: Destination Folder Already Exists is a common WordPress error that generally occurs when installing a theme or plugin. It usually happens when a previous attempt to install or uninstall a theme or a plugin has failed, leaving behind an empty destination folder.

Despite the inconvenience, “Destination Folder Already Exists” is a WordPress error with an easy fix ‒ it involves removing the unused destination folder. You can do so by accessing your WordPress website’s server and removing the folder manually.
