R2.1.0: Bug in list.files
Yes I missed the NEWS entry - or rather didn't realise its significance. So the "bug" was in the previous version and my old code which worked but shouldn't have. Thanks for the replies - rapid and to the point as usual. Steve.

Bug? or have I missed something
You missed to read the NEWS that tells you:
o The regular expression code is now based on that in glibc
2.3.3. It has stricter conformance to POSIX, so metachars such as
{ } + * may need to be escaped where before they did not (but
could have been).
Probably you want
list.files(pattern = "\\.zip$", full.names = TRUE)
