This is expected because when you do a checkout, the timestamps and other metadata of the files are written into the index. This is what makes `git status` work quickly: if the metadata of the files hasn't changed, Git doesn't have to re-read them to verify their contents. You definitely don't want to delete that because you'll likely end up with corrupt data. If you want to create multiple worktrees, use `git worktree add`, which can create multiple worktrees that each have their own index, but share the object store. When you're done with it, run `git worktree remove`, and everything will be cleaned up. Note that with worktrees, you can have at most one worktree with a given branch (or detached head) checked out at a time. -- brian m. carlson (he/him or they/them) Toronto, Ontario, CA
