What do you need to know?

If you want to add the blk0001.dat & blkindex.dat to the wallet folder in Windows to speed up syncing of the wallet;

Go to start > search > then copy/paste %appdata% in the box > click on roaming > find folder newyorkc > paste the 2 files

Advice: to be safe and able to restore your wallet if needed first close wallet & copy your wallet.dat file somewhere, preferably on a usb drive.

On startup the wallet will take some time to load the blockindex, if it seems like its not responding just leave it be...
After that your wallet will need some time to fully sync should take 1 or 2 hours or so I think.
