You'd need nsILocalFile for that, not nsIFile.
Also, NS_LITERAL_CSTRING is preferred to nsDependentCString for 
literal strings; and InitWithPath takes a unicode string, so you'd 
need NS_LITERAL_STRING (note missing C).

However, as you're in C++, you have this nice helper method:
nsCOMPtr<nsILocalFile> result;
nsresult rv = NS_NewLocalFile(NS_LITERAL_STRING("/home/adele", 
PR_TRUE, getter_AddRefs(result));
if (NS_FAILED(rv)) {
 // error handling
}

I tried this code and got the following errors:
macro "NS_LITERAL_STRING" passed 3 arguments, but takes just 1
`NS_LITERAL_STRING' undeclared (first use this function)
Do I miss any header files?

I missed a ')'.
