What are the main ESM Files? Anyone know any info on them?

[The Hat]

Starfield.esm - Understood to be the mainfile

*sfbgs021.esm - I 'think' this is the free observatory mod from creations

SFBGS006.esm
SFBGS003.esm
SFBGS008.esm
SFBGS007.esm
Constellation.esm

Any info on any of these other masters would be great. Are they all needed?

Click on them, then click 'Details' at the bottom below the list of files.
It will list every formID in the file.
SFBGS003.esm is bounty hunter stuff, some armor, plasma cutter+mods.

What "details" are you talking about? I can browse through the files it he Data folder but it doesn't tell me what the mod actually is. File properties is useless. Or are you talking Creation Kit? Vortex won't let me simply disable the crap tracker mod "feature". I want that mod to be totally absent from the game, but God Howard won't allow it.

While in the creation kit, once loaded, top left the folder icon (Load Master/PluginFiles)
A new window will open with all the masters in your game. Highlight one and select details on the bottom.
