i haven't tested this code...

Having a variety of test cases is important. I admit I haven't tested your code myself, but if you had tested it with multiple cases, you might have found that, for example, sort @exts; isn't doing what you want. Also, I can warmly recommend one of the filename manipulation modules like Path::Class, or perhaps File::Spec (a core module) - if you use the former you can even use its methods to list files in the directory (->children). A few more suggestions: Be careful with if ($folder), since that will test negative when $folder happens to be "0" (Truth and Falsehood), you probably want to use length or defined tests instead (same goes for if ($type), of course). Also, I think you might have missed a /g on your "remove dots" regex?

Update 2019-08-17: Updated the link to "Truth and Falsehood".
