CBR/CBZ performance about darkthumbs HOT 3 OPEN

I've done more testing and, if I turn Sorting off, sometimes the right cover is shown, sometimes the wrong one, but I'd say that more often the wrong one.

As for speed, I said somewhere else that each thumbnail takes one second to be produced. I may have exaggerated: it could take one second to produce a couple of covers.

To enhance the speed what I do is instead of "compressing" I tell Winrar to change compression method from "normal" to "store". It makes a .zip file instantly and any application can open it lightning fast as no one has to 'decompress' anything. I do this because the compression method "best" only saves -1% space, takes 21 seconds to complete and takes a lot to decompress for the thumbnailer and any comic viewer. Check this 200 pages manga example:

Not worth it. JPEG and JPG are already a compression method so we gain nothing by compressing less than 1 percent. Only slowness everywhere. If the manga/comic is PNG or even better BMP then yes, compress it. But I only select "store" as my compression method to enjoy the advantage of not having hundred of thousands of images in folders and just some CBZ files around.

To have CBZ files just rename the ZIP file. To mass rename I recommend a renamer like https://www.den4b.com/products/renamer

Enjoy Life.
