Save to option on the Properties

Hi,

I am trying to save the properties in to a file.
It is being saved to the file but in a randomly fashion.

Say I have properties like

myprop1
myprop2
myprop3
myprop4

After saving to the file it is being saved as something random way

myprop2
myprop4
myprop3
myprop1

Is there any way we can exactly load the same to the saved file?
