2 Q's: Show file extensions in ES? Scrape only folder name?

[gold64]

Hi there. Sorry to double up, but the two questions are related I think:

1. Is it possible to have EmulationStation display file extensions? I have about 400 C64 games in various file types, and I'd like to see what type of file they are right in the games list, instead of digging into the game data menu in ES.
   C64 is the only platform I want this for, my other platforms are fine as is.

2. Is there a way to scrape each game's folder's name, and not the files inside the folders? I have my c64 games mostly in individual folders, because I also have their scanned manuals and .m3u playlist files, and I like having the savestates save there as well.
   I can select each game folder manually and use the built-in scraper, but I don't know how to scrape a bunch of folders at once without also scanning their contents. I don't really need the individual disk files (in the case of multi-disk games) scraped, just the folders.
   I also have Skyscraper installed and typically use that for my other platforms, but I don't know if it can scrape just the folder names? I'll keep searching in that area.

Thanks for any ideas.
