I run an Asus T100 laptop with 32Gb disc size under Windows 8.1.
After I had cleaned out data files I had 4.1 Gb of free space. I installed an application which I run successfully on a Windows 7 machine. As this application requires the Java runtime environment I also downloaded that and installed it. Much to my surprise I then only had just over 2 Gb of free space left. I then uninstalled the application and the Java runtime environment but spacewise that doesn't make a difference. The System Volume Information folder has a size of 6.2 Gb.
I wonder if something got corrupted. Without sufficient knowledge about the function of this folder I am loath to do anything rash without advice. I hope someone can give me some guidance.
I have run a virus scan with Avast and a scan with Malwarebytes. These scans didn't show up any problems.
