I've just downloaded the latest Tomtom files for the UK. I downloaded to seperate sources as one download was just maps and the other had poi's etc.

When I look in the respective map folders one has several files (fbl, fda, fpa, fsp, ftr) which is what I am used to but the other download has only one large fbl file (by large I mean the size of the individual files together).

Is this correct? And which one do I use?

I would imagine that the larger map file has the separate files included, if you install the larger file what shows up in about/more/content?

I'd be inclined to use the separate files myself.
