Convert .daa Files to .iso Files for Free With Linux

Have you ever downloaded a torrent only to find that it is a .daa file and not a .iso file? Even though .iso file format has become a industry standard there are still some people that insist on using the .daa format.

The problem with the .daa format is that it is a proprietary file format developed by PowerIso for disk image files. What this means is that in order to use these files you must use poweriso which costs money. There is a trial version you can use for windows however it has some size limitations and it never did the trick for me. Your mileage may vary. So after a little digging it appears that poweriso gives away their Linux version for free. The source is not available however a binary version is, you can download it from right here.

The tool is very easy to use, just unpack the archive and run the binary like you would any other.

Running poweriso -? will get you all the options
