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
What is the name of the file system? Is it D.FS? Actually, I am the developer of Z.eSystem, and I would recommend that you add a journaling feature.
