Here is another important information.
If you want to file your wallet.dat not place on the C drive and was located next to your wallet (in the folder diamond), then you need to create a folder called
diamond next to the file diamond-qt.exe and the label (diamond-qt.lnk) with replace the directory boot blocks .
For example: your wallet file is located on a removable disk H: in the folder Diamond. Then in the file diamond-qt.lnk should be spelled out
H:\Diamond\diamond-qt.exe --datadir=H:\Diamond\diamond
Starting wallet will be through the
diamond-qt.lnk and all files purse can be located on any drive.

I hope that this information will be useful.
