Mac OS Utilities
Rename This! allows you to quickly rename your TV shows' episode files based on show title, season number and episode number and title. It fetches show information from the Internet and also allows you to manually manage the data (just go to Preferences). You can choose one of the six default patterns for renamed files or you can create your own.
Here's how the app works.
First, you should have your episode files organized in the following folder hierarchy: Show name/Season/[all your episode files for that season]. This is not a strict requirement, but it helps the app "guess" some of the information.
Then, you select (or drag-and-drop from the Finder) the folder containing your episodes (the season folder). The app will try to guess the show and the season. It will ask to update the show list and the episode list from the Internet if it can't find a match.
You then have to check if all the files are correctly matched to the corresponding episodes.
In the end, you choose how the files should look like once they're renamed (by choosing a default scheme or by creating one) and click 'Rename!'.
Fixed some layout issues (which should have been fixed in the previous release but unfortunately were not).
Switched sources for episode info, since the primary source I was using is experiencing some problems (episode list is often incomplete).
