Why can we not just see the files in the file manager? No different from Android or WM in this regard, or a Windows computer for that matter. The argument that people could screw things up could be extended to those OS's as well. Seems ironic a device designed to be free and open is the most awkward to access files in of any OS I have used.

Sure, in Windows you have to activate the viewing option and Android you have to get an app like Astro file manager. Point is you can access the directories while using the device and edit, move, copy etc. without command lines.

Something as simple as changing some Doom wad file names is an example. I should be able to view them in file manager and be able to change the names or delete them. Having to run command lines in terminal for everything seems a tad primitive and if anything, invites more potential for error.
