World folder spawn coordinates?

I replaced the '' world '' folder in Filezilla with another '' world '' folder because I wanted to have our old Minecraft spawn again and wanted to ask now where to find the coordinates of the spawn. I'm still on the old spawn and wanted to ask if the 'world' folder contains the coordinates of Worldspawn or something like that.

If you are still standing at the old spawn but have uploaded another spawn, you probably will have done something wrong.

Did you disconnect the server BEFORE you uploaded the other world?
