About .NRG files
What a .NRG file is, and where it comes from.
An NRG file is a proprietary optical disc image created by Nero Burning ROM (Nero AG). Because Nero is rarely installed today, the fastest route is to convert the NRG to ISO using the free AnyBurn or nrg2iso utility. Windows 10/11 then mounts the ISO natively by double-click. You can also open an NRG directly in PowerISO or IsoBuster to extract its files without Nero or any conversion.

Can I open a 4 GB+ .NRG file?
Yes. The viewer never loads the whole file. It reads the disc's directory structure piece by piece, so even large DVD and Blu-ray images open in a second.
How do I know if an ISO is bootable?
Look at the Boot panel. If the image has an El Torito boot record, we show whether it boots on classic BIOS PCs, on UEFI computers, or both.
I have a .bin and a .cue file. Which one do I open?
Open the .bin file: it holds the data. The .cue file is a small text file describing the tracks; drop it on its own to see the track list.
Can I browse a virtual machine disk (VHD, VMDK)?
Today we show the disk details and partition table. Browsing NTFS, ext4 and other file systems inside virtual disks is on our roadmap.
Is anything uploaded?
No. Your .NRG file is read directly from your device by your browser.
