uninstallation of an application doesn't remove files in ~

Question

I uninstall wine 1.6.1 from software center, because I will install a higher version of wine by compiling from source.

But the uninstallation doesn't remove those files in ~.

~/.wine/drive_c$ ls *
os433025.bin

Program Files:
Common Files                            Internet Explorer  Microsoft Visual Studio    NewSoft           Ultrapico

Why are they not removed? Are there some reasons why they are still worth keeping?

If I want to remove all the files of an application, that are not used by other applications, which command shall I use?

Answer 1

The "purge" option to apt-get should remove the package and associated configuration file(s)...

sudo apt-get purge <package_name>

The apt-get man page (http://manpages.ubuntu.com/manpages/trusty/en/man8/apt-get.8.html) says,

purge is identical to remove except that packages are removed and
purged (any configuration files are deleted too).
