If on Windows, explore to %APPDATA%\Bitcoin, rename wallet.dat to wallet-old.dat.
On next launch of Bitcoin-QT a new, empty wallet.dat will be created. 
This will not require re-downloading the blockchain.
Remember to use Settings, Encrypt Wallet on the new wallet.dat.</p>

<p>How can I delete all addresses from my Qt wallet without having to download the blockchain all over again from the scratch? I would like to find a bulk way to do it as there are a few thousand addresses I need to get rid of. These addresses are empty and they only cause significant delays to my interactions with the wallet.</p>

<p>I found a similar question indicating Pywallet (<a href="https://bitcointalk.org/index.php?topic=34028.0" rel="nofollow">https://bitcointalk.org/index.php?topic=34028.0</a>) as a solution but I have to manually remove each address one by one with it, which is not efficient in my case.</p>
