Where can I change appdata local folder location?
Where can I change the User\AppData\Local folder location?
Is that where the files get stored while I am exporting raster to a .sqlite format?

Are you exporting the raster as an RMaps or MBTiles data set?
For MBTiles, you can specify the tile location on the MBTiles Export Options | MBTiles Options tab, and choose whether or not the tile files will be deleted.
For RMaps, you will need to modify the registry. Put the full path to the location where you want temporary files to be stored in the TempDir string value under HKEY_CURRENT_USER\SOFTWARE\Global Mapper. Note that the tile files will be deleted after the RMaps database gets created.
