This files are zipped so they look smaller but once unzipped and installed they will
reflect the real size. In order to see it you must have a back up of the entire tool all
softwares in your computer then go to a folder name scan then vehicle, there you will
see every region and then every make, by doing a right click on the make folder
(gm,ford,etc) then going to property it will show the actual size in kb,mb or gb,
killobite,megabyte or gigabyte. When comparing this folders to an older update folder it
reflects been much bigger in the past for a few vehicle makes than they are now.

 The best thing for you to do is back up your tool before every update. That way if you feel there is a issue with a update whether it be a lost function/pid or just not working correctly you can roll it back to a previous update that did work or can roll back to see if it every actually worked. 

  you only need to copy the SCAN folder.there you have.,
