The "Emacs doesn't have a file-tree" is when I stopped short and wondered what this person's background is in IDEs. My emacs days are 1999 during my "functional or get out" phase, but my .emacs had close to 4000 lines in it, including xterm mouse support, a clone of midnight commander + sftp to a wehbost and deep integration with ctags/cscope/c++filt. There was even a line by line debugger with custom .gdbinit comman…
Sigh. Long time ago, in mid-2000-s I tried to switch to Emacs or Vim from Visual Studio. I wanted to have a simple project file tree as a side panel and multiple editor tabs on the right. I spent a week toying with various elisp scripts, Vim plugins, and digging out information from a then-moribund XEmacs mailing list. And I couldn't do what I wanted in the end. Nothing worked seamlessly or reliably. Can this be done…
Yes, with built-in packages there are at least two different ways - speedbar, or Dired in a side window. And what even "out-of-the-box" means? In Emacs-land packages are not like extensions in other editors and IDEs, they more like recipe books. You can collect literally over a thousand of them without ever explicitly loading them until that specific moment that happens once in a decade and you won't ever notice their presence until then. And there are tons and tons of different packages that do the sidebar directory listing - treemacs, dired-sidebar, dired-subtree, direx, ztree, etc. You seriously thought that in 50 effing years nobody, just nobody thought of making a sidebar directory tree that works in Emacs?

Skill issue. You. You couldn't figure it out. And then decided it can't be done, period. Brilliant.
