  If you're going to modify your database (I think you need to), then you should copy the file from |R| to |D|. But I realized that neither os.* nor lfs.* provides a file copy function. If you want, you can use this implementation:

  local function copy(src, dst) local srcf = io.open(src, "rb") local dstf = io.open(dst, "wb")   local size = 2^13 -- good buffer size (8K) while true do local block = srcf:read(size) if not block then break end dstf:write(block) end   srcf:close() dstf:close() end

  Also it's better to check if you have already copied the file previously with this function:

  local function exists(file) local f = io.open(file, "rb") if f == nil then return false end f:close() return true end

  Now you can copy your database file:

  if not exists("|D|database.db") then copy("database.db", "|D|database.db") end
