Title: BitCoin-QT upgraded from < 0.8 to 0.8.1 Data Directory Q Post by: Kaega on March 25, 2013, 11:10:29 PM According to https://en.bitcoin.it/wiki/Data_directory the blk*dat files in same directory as the wallet.dat are only for pre-0.8.0 and subsequent versions use the "blocks/" subdirectory.
Now that I'm at 0.8.1, why did the client leave both sets? Is it safe to remove the ones in the base level (at same level as wallet.dat)? The dat files are something around ~6GB and now I have essentially two copies.

If they would have deleted the files already, switching back would be more difficult. Maybe they delete them automatically with 0.9 or so.

Only blkindex should actually be using disk space, as the old BLK000x data are moved upon upgrade, and the blk000x.dat files you see there are hardlinks (shortcuts) on any filesystem that supports hardlinking.
