I've been using FarFinder for a while to access my files at home from other places - and it works like a dream. And because I can use ANY computer to access my files, I don't even need my laptop with me. FarFinder is Brilliant for doing this file access from aFar.
I see comparisons have been made - see suggestions in the info box - with DropBox. This is unfair on both products because they are cater for very different needs. I use both and use them for completely different purposes.
With Farfinder I can access ANY file on my system- including files on attached (and shared) external hard drives.
With DropBox I can access - including via their web site - any files in my DropBox - in my case this is a tiny fraction of the files on my system. They are usually critical files - and of course with FarFinder I have access to these too.
I use DropBox to synchronize my critical files between two locations - I call it instant off-site backup - back to my home iMac when I'm working on my files at work. I simply drop my backup files into my DropBox and my MBP and almost immediately I can see them in FarFinder in the DropBox of my iMac at home. I need DropBox installed on my MBP - but that is no problem. It is actually 3 locations - including DropBox web site.
For this offsite backup, DropBox is wonderful - for accessing ANY file on my iMac at home from ANY computer ANYWHERE, FarFinder is wonderful - horses for courses. Both excellent products that I would not like to be without.
BTW - I also use Microsoft Live to synch files between 2 distant computers - it works just like DropBox but without the web site in the middle - so both computers need to be online - free and very fast and almost instant.
