For cbz files I use springy to browse and delete files from the comic archive, it's perfect for what I want to do.
But when it comes to cbr files springy doesn't make any changes, I click delete, the app tells me the file was deleted but nothing actually happens to the cbr file.

Stuffit is out of the question because I can only delete one file at a time, open the cbr again, delete one more and so on. Plus, I don't get image previews from the comic archive.

So, what I want to do is browse/open the cbr/cbr archive without extracting and delete files from within the archive. (tried zipeg but it can't delete files at all from the archive)
