HTML Import 2 – Oops can I revert redirects for WP system files that I imported?

Hopefully someone can help with this…I accidentally imported some of the WP-content files (in the plugins folder for example) so now they’re redirected to my site URL! I’m assuming this is not OK? Is it possible to undo this?! I’ve searched everywhere for help with this but can’t find! I understand it’s not possible to undo the import, but is there a way I can change the WP files that shouldn’t have been imported back to how they’re supposed to be? Maybe in the .htaccess? Thanks in advance for any help! ??
