Windows has a tool called "Disk Cleanup" (German: Datenträgerbereinigung).
There it lists "Debug Dump Files" which can be deleted.
Unfortunately it doesn't tell me which files are meant. It can't be only the folder C:\Windows\Minidump
because in my case it tells me that it would delete 5.65 GB, but the Minidump Folder only contains some KB.
Where are the files located which will be deleted?
