IGreat list. thanks. f you are not using Sergei Strelec's WinPE , what´s the best place/source for your listed apps?
because mpv runs faster than vlc, clean, and for my use (watching movies, series and some mp3) is perfect. i just don't need the many option that vlc offers.
try RoboCopy, it comes with Windows. mt command line switch is for multi thread. there are various gui for it. I like CopyFile (sourceforge) too, it has nicer UI than most commercial-copy programs (such as teracopy), also Locate32 (sourceforge as well) which I've used since forever, and recently found out it can run in a portable mode where the settings get stored ini files.
7zip is on the Apps page under Utilities at portableapps.com If you run their platform you can get it also.
