A hierarchy of folders Inside are pdfs, markdown files, images, schematics, mind maps I frequently review them, shift things around I have a set of spaced repetition folders which topics I am currently memorising go up and down depending on how easily and quickly I recall them when I test myself I let the categories form naturally I don’t try and “big design up front” The folder is regularly encrypted and synced to an always on android phone I have as a wearable computer (it has other functions too - personal llm output, on the mesh net to my personal cluster etc, connected to Bluetooth bone conduction headphones so I can hear while getting audio messages) Works well, accessible on phone, laptop, any machines, it all resides on my NAS
