Accessing Windows drive letters under cygwin

If a drive does not have an explicit mount point configured Cygwin will default to an imaginary mount point under /cygdrive. So “c:\windows\system32” becomes “/cygdrive/c/windows/system32”. (In most cases it’s best to change “\” into “/”.) 
 You can also create an alternate mount point and mount the drive there: 
 $ mkdir /c $ mount c:/ /c 
 In this case “c:\windows\system32” becomes “/c/windows/system32”. Run “mount” to see the current list of mount points.
