This is an indication that this part of the index is using a file format introduced in Lucene 4.1. Here's what I have for one of my index segments on a Solr 4.6.1 server: _5s7_2h.del _5s7.fdt _5s7.fdx _5s7.fnm _5s7_Lucene41_0.doc _5s7_Lucene41_0.pos _5s7_Lucene41_0.tim _5s7_Lucene41_0.tip _5s7_Lucene45_0.dvd _5s7_Lucene45_0.dvm _5s7.nvd _5s7.nvm _5s7.si _5s7.tvd _5s7.tvx It shows the same pieces as your list, but I am also using docValues in my index, and those files indicate that they are using the format from Lucene 4.5. I'm not sure why there are not version numbers in *all* of the file extensions -- that happens in the Lucene layer, which is a bit of a mystery to me. Thanks, Shawn
