<p>Can I safely rename the cygdrive folder? Also, I would like to add other folders at root and map them to folders on windows in the same way as /cygdrive/c maps to my C drive. Is that possible?</p>

I wouldn't rename cygdrive as I don't know what that would do, but you can map other directories at root to various windows directories using the
```
mount
```
command.
