I have emailed Ahead Software to let them know how I feel about them taking over a broadly accepted and established file association without asking: [email to their support alias below]:....
When I installed Nero 7 Ultra on my XP SP2 machine, I told it NOT to take over file associations. Nonetheless it went ahead and associated .NEF/.nef with Nero Encrypted File or fomat.......Nikon uses and has used for years .NEF as the extension for their RAW Files from Nikon DSLRs.....now my 24,000 Nikon NEF RAW files are all associated to some Nero app. That is unacceptable- this is 2007, no program takes over a file extension that is in broad use and accepted by Adobe, Microsoft, Apple and others as Nikon's RAW file format!
There are a few links below on this as well, but I'd like to know how to fix this and re-asssociate the files with Nikon Capture NX and/or Photoshop!
