Steam indefinite update paused

So recently I had an issue with Steam where the Witcher 2 update got stuck at 99% and the status “Update Paused”. No matter what I tried with the pause/resume button, I couldn’t get it to budge from this status and actually update.

After a while I grabbed Process Explorer from the Microsoft website and checked the files that were being opened when I toggled this state. I noticed a reference to Steam\steamapps\downloading\20920\CookedPC\pack0.dzip. Then I also noticed a file reference to Steam\steamapp\logs\content.log. Upon checking that file I found a notice that it was trying to preallocate about 11 GB for this pack0.dzip. Checking my drive status, I saw that this particular drive letter only had about 9 GB left. Freeing up some space allowed the update process to actually start and finish, after which I got even more space back, since it seems Steam downloads these files and then replaces them, deleting the temporary one. So I guess the lesson learnt is that you should always have enough disk space free as the single largest file in any of your games.

  1. Thanks for this solution! Wasn’t to be found on Steam forums or elsewhere.

    I had deleted a few data files believing they were corrupt, and figured I could just re-download them. Apparently it needs several GB more hard drive space than the end-result size of the files.
