I am curently developing a file system for my OS (D.eSystem) with the version 6.1.0.5. The file system is now not working,but it is in development, you can find D.eSystem 6.1.0.5 here: https://github.com/D-electronics-scratch/all_D.eSystem_versions/releases/tag/v.6.1.0.5
I had this idea for a while that I wanted an OS that lets the user have the ability to build their own folder system framework. I moved to linux from windows a year or two ago and the linux file system structure is still the bane of my existence. Which even tho was one of the least obnoxious part of the obnoxious windows file expolere but only because how obnoxious everything windows touched was.
