Same DataStore As Last Time

So, my data from the last datastore is still showing, even though I deleted that script. Is it because I still have the same variable name? Or all the datastores I created are still there somehow?

You must remove it with GlobalDataStore | Documentation - Roblox Creator Hub.

Can’t I just use this plugin: Free Datastore Editor plugin! [21K installs] [OPEN-SOURCE]

You can use the plugin or script. It’s on you!

You can do it in the command bar.

local DataStore = game:GetService("DataStoreService"):GetDataStore("") -- Name
local playerKey = -- Key + Your user id

Cool! How can I use it to delete a datastore. The tutorial is not quite clear.

You can’t delete a datastore.
You can only delete the keys from it.
That’s how roblox datastores work.
