Ubuntu server 20.04.1 with Kubuntu Desktop.
I have tried lots of tools like Baobab, Kdirstat, Qdirstat and Filelight. All show my root to be about 30 GB. However Dolphin(File Manager) and all the partition managers insist my root is nearly full.
Please help me find where the hidden files are. There are nearly 50 GB of unaccounted for files.
