Obsidian uses folders to hold files. My folder/file structure in Obsidian used PARA and PPV as examples (although others may be similar). The top-level is just the Obsidian vault I've called BYLOS, with the top-level folders providing structure for my organizational and data elements. The numbering allows for display organization.
The "00" level of folders provide support for FAKRA
00-Atlas: contains Indexes and Maps of Content to help navigate our Obsidian Vault
00-Calendar: contains date oriented information
00-Inbox: holds incoming information which requires additional review, development, organization
Level "10" through "50" are the core of FAKRA
10-Focus: contains a representation of the areas of your life that indicate where you want to or need to spend your time
20-Activities: contain support for managing our time
30-Knowledge Garden: a place to cultivate and grow your knowledge
40-Repository: the place to store data, in-process and complete information
50-Archive: the place to store completed work or consumed information where the source reference is still needed, or history is useful
Level "90" holds Obsidian support
90-Bins
