I'm currently using KeePass 2 and syncing them via dropbox. I have a few KeePass files (one for websites, one to store software licenses, etc...)
Every time I need a new KeePass file, I just create a copy of the kbdx file, open it, remove all existing entries, change the key transformation rounds to another pseudo-random value.
I do not change the master password.
I want to know if this was unsafe practice, or was a security risk, compared to just creating a new KeePass file via the "File-New" menu.
The reason I don't use the menu: i'm lazy enough to not want to reconfigure "database settings" every time.
