Sounds like you got it and understanding correctly. 👍
As for dropping the word "Season" in front, that is where I place the Name of the Series/Show so I don't accidently overwrite anything and provides me a bit of description in the Roku Media Player. Once you get a lot of files in place with just numbers in folders, can get a bit confusing. You just have to come up with a naming scheme that works for you.
For me, each episode gets the Series Name_SeasonNumberEpisodeNumber_EpisodeTitle scheme.
In your above example for Big Bang Theory, it would look like this for me using your number scheme.
BigBang_S001E001 Pilot (This would be in my BigBangTheory folder, with another season folder named BigBand_Season_001)
BigBangTheory -->BigBang_Season001-->BigBang S001E001 Pilot
BigBangTheory -->BigBang_Season001-->BigBang S001E017 The Tangerine Factor
[The above will list and play in chronological order from episodes 1-17 when you select the BigBangTheory/BigBang_Season001 folder.
Then when you get to Season 12, you should have 12 season folders in your BigBangTheory folder.
BigBang_Season001, BigBang_Season002, BigBang_Season003...BigBang_Season010, BigBang_Season011, BigBang_Season012
Inside BigBang_Season012 you should have 24 episodes.
BigBangTheory -->BigBang_Season012-->BigBang S012E001 The Conjugal Configuration
BigBangTheory -->BigBang_Season012-->BigBang S012E024 The Stockholm Syndrome
You can add or eliminate underscores as you wish of course. S012E001 can be rewritten to S012_E001 if you want. Can also do the same for the episode titles at the end. The Roku Media Player will scroll titles so they will become visible if you give it a second when you highlight the episode in case your naming gets too long to see as a static entry.
I prefer seperate folders for each season, but you can certainly place all episodes into one folder as mentioned by @011 and number them accordingly.
Feel free to post back if you need more help.
