When I say FW preferences or options, this is not the prefs into FW, I'm talking about prefs stored in your disk.
On Linux, it is indeed in /home/user/.frostwire/ (you have to see hidden files)
On Mac, /user/library/preferences/frostwire
on WIndows it is (you have to see hidden files) C:\Documents and Settings\user\Application Data\frostwire |
