So after my issue with data loss I'm proactively taking steps to reduce threads against data loss, spam, and security. My public_html folder contains many files that are no longer in user, including an old wordpress installation, files from vbulletin, old xenforo add-ons I haven't used. I've already deleted most of those but I wait to safeguard against any security breach that's taken place or could. My question is: To ensure I remove any old files no longer in use, can I remove most of my public_html content, re-upload all xenforo core files, re-upload the latest version of the xenforo add-ons I'm using? Are there any problems with this? Obviously I'd have to ensure .htaccess, config.php, /data/ and /internal_data/ and any old vbulletin redirect files remain, but aside from that is there any issue re-uploading everything to remove any old/unused/potential risky files?
