Recently i have had a couple of crashes in games both modded and non. The problem seems likely to be my internet/harddrive as having Steam validate files it finds incomplete or missing files and redownloads them . Not too big of a deal with Steam it repairs the files, but has been a much bigger problem with mods, I have downloaded a couple of 1GB+ mods three times or more (1st with MO then manually) sometimes it fails to install others it installs and the game crashes and when I test archive with 7zip it is always missing data(different data each time), I was wondering if there was a way to repair these archives and download only the missing parts so I don't waste my time and your money. (short version) can I repair downloads to prevent wasted resources?
