RH11 gives a duplicate file error message converting from RH9

My project has an empty file which cannot be deleted but was ignored by RH9.  In converting to RH11 I get the following message: "Error - node */Views/<folder name>/<folder name>/SBLCRVAL.htm already exists."  However, there is no other file by that name in the project.  There is a similar one which I renamed and everything works fine in RH9, but I cannot convert to RH11.
