Is it safe to delete all files found after running Disk Analyzer?
Hell no - Don't do that.
Disk Analyser scans the selected drive looking for files chewing up space.
Deleting any of them could either break software, break Windows or you could lose personal files.
It all depends on what you scanned for and what you are trying to achieve.
Thanks for that. Very good information. I'm pleased I wasn't tempted to delete them then. I guess if you choose to scan for 'Everything' you need to scrutinise before even thinking about deleting.
