I've tried many ways to do this and none of the scripts worked. Such as like:
for i,v in pairs(player:WaitForChild("PlayerSkins"):GetChildren(child)) do
v.Name = child.Name
v.Value = child.Value
end
That and other methodes that didn't work! I'm getting frustrated since I'm looking for a solution for 1 entire day. If someone knows how to save values inside a folder and load them when a player enters I would be really really gratefull. For real, help someone.

What are you trying to accomplish? Do you want to save a player's skins? Also, GetChildren() doesn't take an argument I think
I'm trying to save ALL the values in a folder and I can't figure out how to do that, I guess that you can't use the for i loop to loop through the values inside and save them since they have no especific name..
