It was the same size as the C: drive, but contained different files. I realised that this was a substituted drive, pointing to a folder on the C: drive. I’m not sure how it got created on my fresh install of windows that had only had a few programs installed. The fix was to type subst Z: /D in the command prompt, which deleted the substituted Z: drive. Author Posts You must be logged in to reply to this topic.
