If you have cache selected and cache an area at a zoom level say 14 then later download that same area with a zoom level 12 and 14 will it overwrite the existing cache if saved in the same file or will there be two of the same tiles save?
Also if i have a few tiles missing at a certain zoom level and select a larger area to download will the existing tiles be downloaded again or only the missing ones? I ask because I only have 10,000 tiles a day and don't want to waist any on tiles i already have.
Thanks for any help
