Aah, my ambiguity. What I am looking for is an OR solution. For example,
Keep file names with "Europe" OR ".ps" OR "53" That is why I have a vNewContainer variable, although file names satisfying more than one string would have to dealt with.

Best strategy to adopt then is to first sort the search items by length. Then run your repeat loop from longest to shortest. If lucky, you will only have 1 or 2 items left in your file list. What matters then is the size of your list of words to search for rather than the size of the original list of files. I was not quite sure to understand the use of your vNewContainer variable. Filter will directly act on your variable such that only the lines that the filter let go appear in the new list. So, in fact, you could code it this way and as with the strategy outlined above, if lucky after the first repeat, vNewContainer wlll be very small. put vContainer into vNewContainer repeat for each item thisItem in vInputStrings filter vNewContainer with ("*!*" & thisItem & "*!*") end repeat ...do something with vNewContainer > Thanks to both Jim and Marielle for their awesome feedback. > Instead of > asking specific questions about the details of your feedback, I want > to ask a general performance question.
