    This kinda looks like a strange function, because of the format a "FileTree" accepts:

    EnsureFileTree({
        ["test"] = {
            ["test.txt"] = "hi",
            ["test.json"] = "[\"hi again\"]",
            ["another-sub-dir"] = {
                ["bye.txt"] = "bye"
            },
        },
        ["another-test"] = {
            ["another-example.txt"] = "real",
        },
    })
]]
local function EnsureFileTree(fileTree: {[string]: any}, _currentPath: string?)
    for FileName, Entry in fileTree do
        local RealPath = if _currentPath then `{_currentPath}/{FileName}` else FileName
        local EntryType = type(Entry)

        if EntryType == "table" then -- This is to be a directory
            if not fs.isDir(RealPath) then
                fs.writeDir(RealPath)
            end

            -- Recursively continue creating the file tree..
            EnsureFileTree(Entry, RealPath)
        elseif EntryType == "string" and not fs.isFile(RealPath) then -- This is to be a file
            fs.writeFile(RealPath, Entry)
        end
    end
end

return EnsureFileTree
