On Saturday, I attempted to reinstall a piece of DLC (99MB) only for steam to force a file verification. It got to 97% in the third stage when it promptly decided that I didn't have enough disk space. I deleted my AP folder (101GB, can always reinstall) to give me 123GB of the 21.7GB it told me it needed on my SSD..."Not enough free disk space" after 14.8GB. Am I going to have to delete my Railworks folder and completely reinstall?
Some extra info Steam says that TS is 207GB (although the size it takes up on my SSD is over 700) This is how much space I have on my HDD and SSD Would a reinstallation onto my SSD affect my HDD too?
I've come across this problem a couple of times with both TSC and tsw. It usually stems from having my steam library across more than one drive. Sometimes I've deleted everything in the steam temp folder and it's solved the issue. Other times it's required a complete reinstall! You need enough free space on the drive that the steam temp folder is using. As it unpacks the files to the temp folder. Often a 100mb download can be close to 100gb when unpacking.
