All IDEs including VSCode have fuzzy-finding for files, and fuzzy-finding for symbols as well. Between these, I never find myself using the file tree, except when it's the best tool for the job ("what other files are in this directory?", file tree manipulation (which IDEs recognize you doing, adjusting imports for you!) etc.).

I actually notice how this pattern is very fast, but I lose a code base's mental map. Coworkers might take longer to open any individual file but have a much better idea of repo layout as a whole. That makes them effective otherwise.

I have worked in monorepos for large codebases. In those, file trees are completely useless because you can't fit the repo layout to your mind. Also, the file trees are so large that when I'd ask a coworker using VSCode to open a file, they'd usually take a few seconds trying to locate it (on remote ssh, it even takes a bit to load files to expand directory as well).

For smaller code bases, I usually read the repo first and I'm able to learn what exists while working through it.
