I mis-imported a directory containing the documents for SQLite named sqlite-doc-3340000 with about 1000 HTMLs in MD - Markdown mode. But after a few hours of importing I found that my C: drive was full and I got 20000+ copies of these HTML, each was repeated about 100+ times. It seems to be something wrong in importing routines, but I'm not sure.
(For the health of my SSD I have removed these copies...)
(If there was options to move my DB onto my HDD, it may become chaos then?
