Path Finder has long been a super full-featured Finder replacement for OS X, and now it has been updated to version 6. I have been trying Path Finder on and off for years now, but finally gave up as it’s pretty much impossible to kill the native Finder completely.
Add to this the fact that the Finder doesn’t suck nearly so much as it used to, and that I find most of what I want with Launchbar and Spotlight these days and I’d all but given up on Cocoatech’s offering. But as v6 adds support for file tagging and batch renaming which – in addition to it’s already impressive line-up of features – might make it worth another look.
