319Gb does seem a tad high.
I would uninstall IDSA, delete the folder, and then reinstall IDSA. Use this uninstaller.
Why is there not a specific category for IDSA? That is one of the mysteries of the Intel forum.
Well yeah. Especially when your C drive is 500GB and you try to install 95 gig of music and you get a message saying you don't have enough drive space for it? You could say things where a bit tight. I deleted the files in the folder except for one necessary file and then ran a bitdefender rescue scan for any security breach but there were none. I checked the DSA again and it ran fine. Everything appears to be working as expected. If it happens again I will do as you suggest and delete the folder and reinstall the DSA. I just wanted to know if there where any precedents for this specific issue but it appears there are none so I am at a loss to explain how this happened? I have two educated guesses. The first I already mentioned and the second. Some kind of peculiar software glitch? You know? Peculiar hardware/software configuration, solar flare etc. Any idea how long the Driver & Support Assistant has been available. My reckoning is, if it's new. It could be a little buggy (May also explain why there is no specific category yet)? Thank you kind sir for taking the time to respond to my questions.😃
