Can you recommend a search and replace plugin?

I recently had some issues with file path changes due to me changing the name of the wp-content folder. I have since renamed the folder back to wp-content, but some of the images still retained the old file path and folder name.

Is there a good and safe plugin for searching the complete database that includes all the subsites? I have used "Velvet Blues" plugin on single install sites, but not on a mulitsite. Also, the plugin seemed to ask for the full URL, not just a set of words, like what I want to do: replace "content-folder" with "wp-content."

Thanks, Joe.
