Thanks Jim and Peter.  Ignoring the filename worked.  The process is still
slow but a bit improved.  I had to slightly modify the substring to match
across the two objects.

n_corp_file <- capture.output(meta(corpa[[n]], "URI"),file=)
n_char <- nchar(n_corp_file[1])
n_char_dir <- nchar(corpa_dir)
# want to start at file(\ = 6 + directory + 2
corp_file <-substr(n_corp_file, 6+ n_char_dir +2, n_char-3)
corp_file <- corp_file[1]

##this doesnt suppress, but works too
#n_corp_file <- meta(corpa[[n]], "URI")
##want just file not dir and file
#n_char <- nchar(n_corp_file[2])
##nchar[1] is "file"=4 and nchar[2] is dir + filename amd nchar[3] is
"UTF-8" = 5
#n_char_dir <- nchar(corpa_dir)
#corp_file <- substr(n_corp_file, n_char_dir + 2, n_char)
#corp_file <- corp_file[2]
#####END of nonsupressed
