Its a suite with all nirsoft and sysinternal utilities.
The best thing is a built in update manager which checks the authors pages for updates.
They even advertise a fully portable paf.exe installer!
(They have a normal and U3 download too but who cares about them? :P)
I think this would be a nice inclusion here. I tried it and it fully portable. Its not too good regarding to paf compliance though. They put all sysinternal/nirsoft apps into the Data folder. But they save their dat/cache there too so its no big deal I think.
What do you think?
