Dropbox does not allow you to set the name of the root folder for Dropbox on your Windows PC. It is always called "Dropbox". If you want to change that name you need to change it manually by editing the configuration file.
As the configuration file is a SQLite database you will need to use a database editor like the SQLite Database Browser.Then perform the following steps:
- Stop Dropbox first.
- Then open the file "C:\Documents and Settings\<username>\Application Data\Dropbox\config.db" with your SQLite Database editor and change the key "dropbox_path" from "C:\Dropbox" to the path you like to have it.
- Save your changes.
- Rename your existing dropbox folder "C:\Dropbox" to the name you want to have.
- Start Dropbox again.
