Anyone know of a freeware alternative to UltraISO or isobuster?
To burn ISOs to disc, use InfraRecorder Portable:
To get files out of an ISO file, use 7-Zip Portable (you can open an ISO like a ZIP file):
Mounting an ISO so it shows up as a drive letter requires administrative rights, so it's not something you'd usually do portably.
Sometimes, the impossible can become possible, if you're awesome!
how to edit and save .nrg image file in InfraRecorder Portable?
NRGs are a proprietary (read: non-standard) format and aren't supported by most CD/DVD burning apps. As such, InfraRecorder doesn't create them.
The only real advantage of NRG over ISO is that you can put an audio CD into an NRG and NRG better handles some discs with copy protection (which is why some warez sites use it).
Have you found anything free/portable to open *.NRG files?
there isnt anything. .nrg files are propriatary and will stay that way. there is NOTHING that will allow you to edit them.
To burn iso image is easy but I want to make iso image to burn later or save.How to make iso image?
InfraRecorder Portable can do it:
Program: AVS Disc Creator
Description: Copy personal home audio in the original quality. Burn data in several sessions on to the same disc. Create your own disc cover with an integrated disc cover creator. Burn boot discs and create password protected file image formats (.daa, .uif). AVS Disc Creator supports CD-R/RW, DVD+/-R, DVD+/-RW, DVD-RAM, Double/Dual Layer DVD and Blu-Ray discs. It also edits ISO images.
Note: I noticed some sites I looked at regard this as freeware, others as shareware. Can't really determine either way for sure from the applications website. Good luck
There aren't any free ISO editors for Windows at the moment. There many image creators and extractors, but not editors.
I only know of a free image editor for Linux. There is also Windows version on that site, but it is not free:
I can't imagine editing ISOs being a normal, everyday occurrence. For when you occasionally need to do it, extracting it via 7-Zip Portable and then creating a new one with InfraRecorder Portable is an easy way to do it. And it's portable and free.
Then again, I don't normally touch ISOs or CD/DVD discs. The only time I've used them in the last several years was to download ISOs of Win7 and Linux for OS installs in VirtualBox. I think I burned the Win7 ISO just to have a disc of it, but haven't used it.
this one is NOW free - support is no longer provided.
i'm downloading the 5.3 version, to run on my XP workstation, however, is the FREE version might be able to be made PORTABLE, that would be AWESOME!
