File extensions problem

[frederick]

Ok, lets say i have a demo called "default.mxdemo" and i want to rename it "demo1"
When I do that windows doesnt recognize the file because i didnt put .mxdemo behind demo1'

Now, all my files on my computer has their file extensions put into their name. And if i want to rename ie a picture, i have to name it *picturename*.jpg/png/bmp instead of just naming it picture1.

This problem occured today, before today, ive never needed to name my files with their file extensions into their name.
Is there a way to get rid of this?

Go to Control painel and propriets of Options of folders or something like that
Double click and go to display mod , you need find something saying about ocult file exetensions and select this option , i hope yo understand this way
