The use of simple patterns permitted by tar(1) or cpio(1) may be a
good choice in some cases, but we were responding to the OP's wish to
use find(1), which is a bit more flexible.  If there were a large
number of files, one could still use find and tar in many cases by
appending to the archive rather than (re)creating it with each tar
invocation, e.g.:

 find . -type f -name '*.txt' -print0 | xargs -0 tar -rvf archive.tar
; bzip2 archive.tar
