There is no undo feature in MediaElch or any of the media managers (that I am aware of).

What is wrong with just doing a search and delete? Search *.nfo, highlight the results and delete? Same with *.jpg and *.png. Obviously I have no idea what platform you are using but in Windows it is that easy.

What are you trying to accomplish? Maybe we can point you to something better suited to your needs.

i guess that's the only way.
it's just there are more than just jpgs, nfos, and pngs. there are also the folders for extrafanart, actors, etc.
some other media managers do actually have a remove nfo and jpg option. mediaelch doesn't though.
