Windows App file locations

I know that there are three versions of the Arduino IDE for Windows:

  • Windows Installer
  • Windows App
  • Portable zip

I also know there are important files and folders the IDE uses:

  • Sketchbook
  • libraries
  • bootloaders
  • preferences.txt
  • boards.txt

I'm wondering about file location differences between the Windows App and the Windows Installer. The IDE tells me the location of the Sketchbook and preferences.txt (File > Preferences), and the libraries are within the Sketchbook, but if I want to edit the boards.txt file or add a custom bootloader, where do I look (especially for the Windows App)?

Thanks,

The .Zip file is not “portable” in the usual sense; it just need not be installed in c:\program files.
You can MAKE it portable (all dependent files in the same install directory), but that gives you a fourth type of install.

Oh, yes, you're probably right about the zip file not being truly portable. I misspoke (mis-typed)?
