I saw another launcher that was custom made for a server, and how it worked was it synced all the files for the modpack. I realy think FTB launcher should implement this. Idea is when a modpack updates, it releases a file that tells the launcher what files to delete, then download.
What it can help:
What it can help:
- Less downloading, which would mean the download servers will get less load.
- Single file updates, it will update the pack really fast. So if a modpack just has to update lets say Industrialcraft, it will delete the old one, download the new one.
