[Wine] Nothing in program files folder??

[ET900]

I have installed a few games and wanted to add some mods to one of them. So I look in my program files folder but nothing is there apart from 'common files' and 'internet explorer' like when i first installed wine. I have 3 games installed and none of them show up there, yet they are definitely installed as i can play them! I tried enabling the option to show hidden files but nothing else shows up. Does anyone know why this is? Thanks!
