?list.files and ?regexp

Warning: following obviously untested:

Gfiles <- list.files("G:", pattern = ".*10806\\.xls$")

should then give you a vector of character names of the files you want to
feed to read.xls() or whatever function exists in the favored package is
for reading Excel files these days.
