HEZMANA Love it, I used to use Yojimbo which appears to be ignored by it's developer. Eagle filer is easier to use, but it does not have the slick interface of Yojimbo. As noted in other reviews, it allows you to use a library that can be placed where ever you want, what an idea. It works great in Drop Box. My Yojimbo no longer worked with .MAC (ME), on any of three computers.
Again Eagle Filer is great, maybe a bit expensive, but worth it.
The only issue I have is that you must encrypt entire libraries and cannot just do one document. Maybe a future feature request.
