some kind of compressed images support

[Development]

Full support will be added according to published specification, including split files.

All,

which tools/appl. will be able to generate compressed images (expect UltraIso with .isz format) ??

[Mesterial]

So, any news about integrating compressed image in DA ??

[Copytrooper]

Next Daemon Tools version will support compressed and encrypted images, so stay tuned. It will be released when it's done.

THANKS for the new .isz feature, it is great! I have been waiting years for compressed ISO support.

Have you considered in adding CSO support in a near future? CSO have been proven to be a good compressed format in PSP world and it is not commercial. However it doesn't compress as much as .isz

I love what you're doing with compressed images, it warms my heart. <3 Will the mds compression be able to handle the elimination of difficult-to-compress checksum data, similar to the ECM tool? Unfortunately, isz doesn't work for me when most of my files have at least some sectors without checksums. And I know this is a long shot, but will it support any form of dedicated audio compression, either more intelligent lossless like flac or even mp3? (Doubtful, I guess, and I'll probably still have to manually deconstruct audio/video in archived game backups, and reconvert when I want to play again.)

Dear DT team,
It seems that some people need compressed ISO, I've asked to write a plugin but 'you' said that only companies/firms can write this.
I've a good experience in a specific Compressed format, that can be used by the Playstation Portable, called CSO
You can have a look on http://cisoplus.ifrance.com
I can easily simulate functions such as fopen, fread, fseek, ftell, etc.
The software still convert ISO->CSO CSO->ISO and even CSO->CSO (with different parameters of compression)
I don't really understand why it cannot be possible to have documentation or only some help to write simply a plugin like nrgmount.dll, bw5mount.dll, ....
Perhaps the code to read ISO is inside the main program?
Can you just give me some information to understand how is hard to develop such a plugin
Thank you
Best regards

It is not possible to make plugin like bw5mount which simply
"simulates" fopen, fread etc for virtual drive because it works in kernel: you need make some driver. Current plugin architecture can work only with uncompressed images or only with some compressed formats which are supported directly in kernel by virtual drive itself: these are currently only ZLIB and BZIP2.

The CSO format uses (and I used) the zlib. There are only inflateInit2 inflate and inflateEnd. The CSO format is very very simple to understand and implement. It's clear that it will produce larger files than other compression schema but I think it will be very interesting to have a look on it.

Thank you for your explications

In such case making plugin for it should be straightforward -
