The location where Bitcoin's data files are stored, including the wallet data file.

Default Location


Go to Start -> Run (or press WinKey+R) and run this:

explorer %APPDATA%\Bitcoin

Bitcoin's data folder will open. For most users, this is the following locations:

C:\Documents and Settings\YourUserName\Application data\Bitcoin (XP)

C:\Users\YourUserName\Appdata\Roaming\Bitcoin (Vista and 7)

"AppData" and "Application data" are hidden by default.


By default Bitcoin will put its data here:


You need to do a "ls -a" to see directories that start with a dot.

If that's not it, you can do a search like this:

find / -name wallet.dat -print 2>/dev/null


By default Bitcoin will put its data here:

~/Library/Application Support/Bitcoin/

Directory Contents


  • database


  • .lock
  • blk0001.dat
  • blkindex.dat
  • __db.001
  • __db.002
  • __db.003
  • __db.004
  • __db.005
  • __db.006
  • db.log

The data, index and log files are used by Oracle Berkeley DB, the embedded key/value data store that Bitcoin uses.
