Actually, these days .del files are even versioned. > I don't know exactly what happened, but I restarted Solr once or twice > and then when I started adding documents again, Solr started deleting > segment files, and brought things down from like 500GB to like 18GB.

Right... file deletion just tends to be delayed a bit longer on Windows. For example, if you do an optimize, all the segments will be merged into a single segment, but because a reader is still holding open the old index, you will see both sets of files. The old set of files will be deleted when a new IndexWriter is opened after the old reader is closed. -Yonik
