Default [Q] Separate downloads folders in Android?

Hello there

I just noticed today that Android gives you the ability to decide where certain file extensions go, as in you choose the extension as well as the folder it would go to. I'd love to do that with pictures (.jpg, .bmp, .gif, etc.), music (.mp3, .aac, etc.), applications (.apk), compressed files (.zip, .rar) and such but I am not sure I know how to go about this.

This is a screen shot of what I am referring to:



If anyone has information about this and exactly how to do it I'd be very grateful.

Thank you very much and have a great day everyone.
