For the differences, have a look here :

If I recall well, older versions of BC allowed for filename encryption and the encryption of a maximum of 2 GB of files.
Currently (starting from summer 2012 ?), the free version of BC allows for encryption of an unlimited number of files, but it doesn't provide filename encryption anymore.
I cannot check the following precisely, because I've installed a purchased unlimited BC version, but the free BC edition:
o) mounts 1 BC drive
o) doesn't encrypt filenames, but
o) allows for the encryption of unlimited files
o) and is multi-platform
In short, you have a GUI-based multi-platform tool for free, a tool that provides on-the-fly encryption of unlimited files.
Client-side, so called zero knowledge encryption technology, as provided by BC, is an important aspect of cloud storage.
Because of catastrophes like this:

and quite some others as described on the web / forums, people have lost their job, lost their customers, etc, because they stored _not encrypted_ customer or company data like text, pdf, doc, etc, files in the cloud.
To summarize:

Even the free BC version is a valuable tool to protect your customer's and other data in the cloud.
In addition, it allows you to experiment with most of BC's features before you buy, which is a generous offer compared to other software systems.
Once you're convinced that a particular version is stable, go for that version.
