Unless the OP needs the entire list of "tens of millions of files", I'd suggest not using File::Find::Rule, and I'd instead suggest an iterator or callback based routine (like File::Find). If you can process files one at a time, there's no need to build such a huge list.	[reply]

runrig, I don't follow you. File::Find::Rule does not simply return every file (although it can). You can instruct it what to return based on type, size, name, and even make a determination via a custom sub. You can have the sub perform actions and ignore the larger return value, or iterate with the `start` and `match` methods.	[reply] [d/l] [select]

Read the OP. I didn't say FFR has to return the entire list, the OP says the entire list needs to be processed. So, in this case, FFR would return the entire list of files.	[reply]
