Yes, I knew.
While I am waiting for bam-bam lighter file (abt 300 MB vs 500), I played with the France Benelux file (although I don't need Benelux). I had to unlock the file with GimgUnlock and I can use that map, but bam-bam file fills more my needs : it is unlocked and lighter.

idem with Spain. I prefer bam-bam Spain map rather than Spain + Portugal.
