By the way, how do you change the flag/nation name in the editor in HoI2? I'm rather ticked off that my Prussia would become Germany without asking me first.
Look in the Db folder. All the basic game info is in txt files in there and it's very simple to understand.
Country names I think might be under Scenarios.
Some files in there are called .eug or .inc but you can open them in notepad. Those files contain the initial playable countries and their setup - eg, provinces, resources, starting units, techs, diplomatic relations, how many AA, naval bases, forts you have and in which provinces etc.
Google "paradoxian" or "Hoi2wiki" for more information.
Revolts.txt which is in the main Db folder I believe has the starting provinces per country, and all what your national provinces (ie, claimable provinces) will be. Provinces.txt is a gigantic file which lists resource, population, starting factories, whether there is a port, etc for every province in the game. The easiest way to change it would be to import the file as a .csv into Excel (so info is separated/sortable into columns).
Techs and tech teams are under Db/tech. Units costs/attributes are under Db/tech/units/brigades...
Events are under Db/events, and are pretty self-explanatory, you just need to be able to follow through threads (trigger event ids and choice consequence event ids) so you should have a paper and pen handy.
I can say one thing for Paradox Interactive, they made the game extremely moddable.
For pictures, look under something like Graphics/interface/pics, and find the picture the game is using. Open it in an image editor, paste in the image you want (without resizing) and save/overwrite, is the easiest way.
