My HTPC is showing some weird drive usage that I can't explain. I last rebuilt it in 2012 and haven't made any hardware changes for years. It boots of a 5 year old OCZ 120GB SSD, in the last 5 years it's been no more than 50% full. Very little is written to it apart from the occasional new app and Windows updates. It runs Win7 for MCE use, recordings are made to a separate 1TB HDD. In the last few months it's been showing no more than 2GB free, but checking the properties of everything on the drive in file explorer (showing hidden and all system files) comes up with 61GB used which is about where it has been for years. Disk cleanup only gains around 1GB, in line with what I'd expect anyway. I have no idea why it's reporting 1-2GB free space on the SSD when no more than half of it is used. Is this a sign that the drive is failing or is there something else causing it? The only thing I can think of that I've installed recently is a copy of Plex server - anyone had any issues with it?
Run treesize on it. There's a very high chance the winsxs folder has grown (my htpc is hitting 70GB+ in that folder)
+rep, showed what was wrong. Not the winsxs folder but Windows\Temp - had to apply admin rights and Explorer says it's empty but it's 49GB according to treesize.
