In my obsidian notes folder, i have

• 01 - Inbox
• 02 - Breadbox
• 03 - Data

.

• Inbox is for newly created notes
• Breadbox is for notes that i need to reference or otherwise want quick access to
• Data is for everything else

For file navigation, i use links and references within the notes themselves, which creates a network of linked files that is far far easier to navigate than folders

Everything else is sorta all over the place, but in general

• ~/Documents
  • dumping ground for important documents, folders are arbitrarily made as I go
• ~/Downloads
  • dumping grounds for downloaded things, generally important files are moved elsewhere
• ~/Code is where i put all of my personal projects and other junk related to programming

~/ is the user home directory

• C:\Users\Name for windows
• /home/name for linux

For pictures, i use a self hosted Immich instance
