Thanks for the replies. Actually, any file can be designated as hidden if you don't want it to be visible or acessible to casual snoops. I keep some of my files hiden in this manner so that nobody can be exposed to inappropriate material accidentaly.
With past versions of WinMX I could share whole directories, then turn off hidden files and nobody looking in my computer could see them but they were still browse-able and share-able to WinMX users. I was just wondering if that is still possible with this new build.
