Hello, thank you for your question.
You don't have to create "spain" folder inside "hsnav" folder.
1. Create folder "tiles" inside "hsnav" or just run "HotSpot
Navigator" and it will create folder instead you.
You will get "E:/hsnav/tiles/" as result.
2. Copy contents of archived Spain map to this folder.
I know it will takes a long time, be patient.
I don't have any problems this huge number of little files on my
memory card, except "Gallery" function.
But you can set "Hidden,System" attribute on the folder "tiles" with
helps of "Windows explore"
or "x-plore" for Symbian platform.
You give me a good idea about zipped map files, I will try to release
that in future releases.
Thanx.
