The different files of AppSync

  • The .asd file is used for keeping track of when last checked the AppSync location
  • The .asl file is used to keep track of how much we downloaded and it contains a list of block signatures for the new file (we use these block signatures to find blocks that we can copy from the existing old file)
  • The .ase is the complete new updated file waiting to be applied as the .exe file (contains blocks both from the old .exe file and from the update file)

If a download is interrupted during AppSync it continues where it left of the next time the user launches the application.
