I also have Forklift 2.x, again, used occasionally. It doesn't show folder sizes (unless you do a Quick Look or a "Calculate Sizes"), while Path Finder 5.x does show that as a column.
ForkLift has sync browsing, something I've liked since 1.x. It has a sync feature (one way sync) to keep folders in sync, something Path Finder does not seem to have.
Similar features between ForkLift and Path Finder 6:
* ForkLift 2.x has a drop stack like functionality implemented differently from Path Finder. It allows multiple stacks to be created, named and managed.
* It also has Multi-Rename, which is just like Batch Renaming in Path Finder 6.
* It has tabs.
The more I look at http://wiki.binarynights.com/ , the more awed I am by ForkLift 2.x. Path Finder 6 has unique features like git/subversion interface, hex editor, terminal window, processes, etc.
With the current $5 off promo for upgrades (too), I'm wondering if I should just upgrade Path Finder 6.x and see if it fits better or is complementary to ForkLift 2.x.
Anyone compared ForkLift 2 and Path Finder 6 yet?
