Sorry if I'm being condescending but I made a really obvious mistake like this just the other day,
are you aware that because the directory name has a . in front of it, .wine, that it is a hidden file.
If you open a terminal, go to your home directory and
it will enter the directory.
Depending on your distro there should be a 'show hidden files' option under one of the -File -Edit -View, menus somewhere.
Also, if you installed this as root, it will be in the roots home directory and not yours.
Like i said, i'm still new to all this, if this is obvious and you already knew or tried, then just ignore me
