Does anyone know how to save something without datastore? Saving a folder

What you have to do is loop through all of the values inside the folder, and save the value of each one in a table.

local function CompileSaveData(Plr)
    local SaveData = {}
    for _,Data in pairs(Plr.FolderHere:GetChildren()) do
        SaveData[Data.Name] = Data.Value
    end
    return SaveData
end

If you gave that example function the player, it would return a dictionary with every value name as their keys, and their values as the values' value (woah thats a lot of values)

Then, you would datastore that table (similarly to how I explain here). When the player joins, you can load this data and re-create all the values with something like this:

local function CreateValues(Plr,SaveData)
    for Name,Value in pairs(SaveData) do
        Plr.FolderName:WaitForChild(Name).Value = Value
    end
end

When you give this function a player along with the loaded data, it will go through the data and re-enter every saved value into the values in their folder. You will have to change the FolderName to the appropriate name in both the examples (such as 'leaderstats' if the values are part of the leaderboard).

Hope this helps!
