I don't know what device you have, but I think that these files are related to the default Touchwiz launcher for your device. This is what provides your desktop, as well as other functions of your device.
Unless you know exactly what your doing, and from your post I would guess you may be new to this, I would leave everything alone right now.
It doesn't take much tinkering to render you device useless.
Just a word of warning.
