Transfering DNG files to WINDOWS 11

I have a Phone 14 Pro v17.4.1, , and many shots are in RAW mode, producing files in a DNG format. One example is IMG_3798.DMG, a 6990x4499 119.2MB file. If I use either Windows File manager to copy over to a Windows directory, it either results in a IMG_6798.JPG with a MUCH SMALLER image/file size or says the format is not supported and cannot copy. However, sometimes it does copy over. I have also seen it change extensions to IMG_3797.AAE, a 102Mb file, where the IMG_2797.DMG file is actually 114.8Mb file. I am comparing files and sized loaded to a MAC Pro, using Photo as the "master" index of what it should be.

This is a relatively new problem -- I have been using Windows/Photoshop to handle my photos for years.

Win 11, V 23H2, current build 22631.3296 (current Mar 2024). When the DNG file does transfer, Photoshop handles it as a RAW file (I shoot Nikon also). When it doesn't I loose lots of valuable file info. HELP ?


Windows, Windows 6

Making DNG Files Transfer Easier to Understand:

DNG (Digital Negative) is like a photo file that holds raw, untouched data from your camera. But sometimes, Windows doesn't know how to handle these files properly, causing issues when you try to move them around.


Here's How to Make Moving DNG Files Easier:

  1. Use File Explorer: Instead of relying on the Photos app, go straight to your iPhone's storage using File Explorer on your computer. This helps copy DNG files smoothly.
  2. Get a DNG Codec: Install a special tool called a DNG codec on your computer. It helps Windows recognize and show DNG files correctly. You can get one from Adobe for free or check your camera brand's website.
  3. Try Cloud Storage: Upload your DNG files to a place like iCloud or Google Drive from your iPhone. Then, download them onto your computer. This way, the files transfer smoothly, no matter what format they're in.
  4. Use Image Transfer Apps: Try using apps made for moving photos, like Image Capture or Adobe Photoshop Lightroom. They're good at handling DNG files.
  5. Check iPhone Settings: Make sure your iPhone settings aren't messing with the transfer of raw photos. Look for options like "Transfer Originals" and turn them on to avoid sending optimized versions instead.


Extra Tips:


Follow these steps, and you'll have an easier time moving your DNG files around without losing any important data. If you still have trouble, look for help on Windows or photography forums, or contact Apple Support.

I have resolved MOST of the issues - I was having some problems with Photoshop Elements 2022 - and upgraded to Photoshop Elements 2024 - It turned out it DID NOT install support for RAW files - and that was causing most of the problems. In the PSE 2024, under the HELP menu is a "Install optional raw" - and once that added the missing features (that should be standard !) I was able to get both my IPhone and Nikon raw pictures in.

What is still open are some curious problems with a few HEIF files that look good on the phone but Adobe is not accepting. Nothing now - I will work on this issue next week if I have time. Thank you for your discussion and help.

Use ProRAW with Photos and other apps

ProRAW uses the industry standard digital negative (DNG) file format, so you can open ProRAW files with apps that are compatible with DNG files. For the best experience, however, use apps that are compatible with ProRAW files, such as the Photos app on your iPhone with iOS 14.3 or later or on a Mac with macOS Big Sur 11.1 or later.

You can share the original unedited ProRAW photo, which has the .dng file extension. And if you edit the photo in the Photos app, you can also share the edited version, which has the .jpg file extension when shared.


Edit a ProRAW file with another app

You can open a ProRAW photo in an app that doesn’t support ProRAW, but it may look different than expected when opened. If the ProRAW photo doesn't look as expected, try using the app's feature for enhancing the photo automatically.


Share ProRAW photos

Here are the best ways to share your ProRAW photos:

  • Use iCloud Photos to access the original ProRAW file in full resolution on all of your devices.
  • To transfer the original ProRAW file from your iPhone to another iPhone, iPad or your Mac, use AirDrop. If you edit the photo in the Photos app and then share it, you'll share a JPG file. To share the original ProRAW file from the Photos app on your iPhone, tap Share, tap Duplicate, tap Edit, tap Revert and then share the photo using AirDrop.
  • To share an edited ProRAW photo with someone else, edit the photo in the Photos app on your iPhone, then AirDrop, email or send with Messages. A JPG file that includes your edits will be shared.
  • To email a ProRAW photo, create an email in the Mail app on your iPhone and then add the photo to the email. The Mail app converts the ProRAW file to a smaller JPG file automatically, which you can then send by email.
  • If you edit a ProRAW photo and want to share both the original ProRAW file and the edited JPG file, use Image Capture on Mac or the Windows Photos app on a PC to import the files. You can also use AirDrop to share both files to a Mac. Tap on Options and turn on All Photos Data before sharing, then select Save to Downloads when you receive the files on your Mac.
  • If you edit a ProRAW photo in the Photos app on your Mac, and you want to use your Mac to share the original ProRAW file only, select the photo in the Photos app, then choose File > Export > Export Unmodified Original.

The windows 11 system had been working correctly for copying and editing the DNG files. Something had changed, and I cannot yet determine if it is Apple IOS or Windows side of the communication. Based on the Apple community notes - it does appear there has been a problem with the DNG files moving, so I made sure both my IPhone and Windows are up to date, Yes, I get the same result with different USB cables, and I also just updated my Adobe from 2022 to 2024 versions incase that was the issue - but when I use Adobe to import, I get much the same strange results. It also complains and suggests I need HEIF drivers, but that has been installed and is also current per MS. I am loath to change, as the Adobe file manager has 30k images all indexed to date/person/location, etc.
