I have a friend use Window Xp and he backup all his files due to virus?

But after the backup he noticed all his picture files are in *.nco extension.

Does anyone know how to convert them all back to *.jpg formates

Thanks

reported image files ending with .nco after a backup. The thread replies point toward a backup/archive container, but the practical first step is diagnosis: determine whether each .nco is actually a JPEG with a renamed extension, a simple archive, or a proprietary backup container that needs its original app to extract.

Make safe copies of the media and work only on duplicates. Quick diagnostic workflow:

  • Inspect the file header with a hex viewer for common JPEG signatures (hex FF D8 FF). 
    JPEG header bytes: FF D8 FF
  • Run a signature-based identifier such as TrID or consult a file-signature table like Gary Kessler’s list.
  • Try opening the copy with a generic archiver (for example, 7-Zip)—some backup containers are extractable that way.
  • If headers are not JPEG and extraction fails, search the file for readable strings with a hex editor (for example, HxD) to spot vendor/product names; that often points to the correct restoration tool.

If the header matches JPEG, batch-renaming the copy to .jpg or using an image viewer will often recover the pictures. If the files are inside a proprietary container and the original app is unavailable, file-carving tools such as PhotoRec/TestDisk can often recover JPEGs directly from the disc image.

This expands on the practical parts of and ’s suggestions by giving concrete identification steps and fallback options (header check, TrID, archive test, carving) while preserving originals and scanning recovered files for malware before opening.

i believe .nco file extension is an Nero BackItUp compressed backup file... if you try clickin the file and selecting the option "Open with Nero backItUp Restore", you'll get a conventional "Save as" dialog box from which you can save the file uncompressed and with its normal extension (jpeg) in whichever location you choose...

So, Ihave a new computer and old back-up files that I need a document from...problem: the old back was done on Nero Burning, and my new computer does not have the program, and I do not have the program, and all the documents/files on the back up disc are .nco extensions...any ideas?

Get a copy of the Nero burning CD. You can download a 30 days trial period and if it works than you buy one. It is good to keep a copy to back up your important files just in case something happen to your computer.
