Viewing Exported to HH map file

[WBFAir]

Hello all

Sorry that this isn't in the HH section but I notice that doesn't get much traffic and as well the topic is not only a HH thing.

I have created a map via blocks that I put in my handheld that is fairly big and I thought would be big enough for my needs per my area but I've found now that is not an I would like to enlarge it by a bit more.

As I don't really remember where all the areas were that I used & I don't want to loose any via making a new one, I was wondering if there is anyway to open that file in SA9+ on my PC an view it as it was before I saved it, then make the changes I would like an then save that.

Kinda a long the same way you might do something like this for a route that was saved.

So is it possible to do this?

Thanks
