Renaming what files? The databases like Gstreet.db? By doing so you would just be creating a new .db file and then have to redownload all the maps again.

Edit: Deleted the Google Street repo and created a new one.. but now I have..

Gstreet.db (the old one)
#Gstreet# (the new one)

o.O

Edit2: Can anyone tell me if SQLITE still uses a .db file? Also does anyone else have problems when they try to download large amounts of map (100+ MB) causing crashes in either Maemo Mapper or the tablet restarting (probably due to a lock up)

Also does anyone know if it's possible to run a virtual version of Maemo in VirtualBox. Since Winmapper doesn't seem to be working with SQLite. I was thinking, if it was possible to install Maemo into Virtualbox, install maemo mapper, download maps through there. Then transfer to tablet.
