Title: Getting rid of unneeded blkxxxxx.dat or revxxxxx.dat in core after re-indexing Post by: Moria843 on December 31, 2015, 08:49:58 PM After power loss and having bitcoin core re-index blocks on drive for about 15 hours, I now have a rev00000.dat ... rev00409.dat for each blk00000.dat ... blk00409.dat file.
Any easy way to have bitcoin core get rid of unneeded files or to manually do without messing things up?

If you delete them then Bitcoin Core won't work.

Never had any revxxxxx.dat files until forced to re-index.

Never had any revxxxxx.dat files until forced to re-index. Some references: http://bitcoin.stackexchange.com/questions/11104/what-is-the-database-for Quote blocks/rev*.dat: these contain "undo" data. You can see blocks as 'patches' to the chain state (they consume some unspent outputs, and produce new ones), and see the undo data as reverse patches. They are necessary for rolling back the chainstate, which is necessary in case of reorganisations. https://en.bitcoin.it/wiki/Data_directory Quote locks subdirectory [v0.8 and above] Contains "undo" data. rev*.dat You can see blocks as 'patches' to the chain state (they consume some unspent outputs, and produce new ones), and see the undo data as reverse patches.
