Unknown issue with .RAW files
« on: June 14, 2022, 07:02:56 pm »

I have been reorganizing my photo library. Moving files, renaming and removing duplicates, etc.
In the folder that I keep photos from my cell phones I have a great number of files with the extension .RAW on my hard drive that Lightroom says it is unable to import. I get a message that the files are corrupted or damaged. This issue is only with files from my cell phones.  In the course of my reorganizing, I do not seem to be missing any files, so I am puzzled as to what has happened and why I now have hundreds of .RAW files that I never had before.
Can anyone help me understand what is going on?

When I try to open them in Photoshop, this is what I get,

Did you do all the moving, renaming etc within LR or in another application?

Do the newly created files with the .RAW suffix have similar file names to other files in your camera folder e.g.  273.RAW and 273.***, If so can you open view the other file?

What is the normal naming convention your cell phone uses for files I.e. “filename.***” and are they really raw or JPEG?.  What happens if you duplicate one of the .RAW files to another location and rename to ****.jpg ? EDIT: or *****.dng

Not here.

These are not raw files, in spite of the name.

Good point they may be DNG or rather already demosaiced linear DNG.  TBH, I do not know as I do not think my so-called smart phone offers a raw choice  :-\.  Have edited my first reply to include .dng just in case  ;D

200 pixels x 128 pixels?  What is that?  Not an image file (not these days or perhaps ever).  A corrupted thumbnail?

I tried in both Lightroom Classic and Windows Explorer.

Do the newly created files with the .RAW suffix have similar file names to other files in your camera folder e.g.  273.RAW and 273.***, If so can you open view the other file?

In some cases yes the naming convention is similar, i.e. 273.raw which will not open, whereas 274.jpg opens fine. There does not appear to be any duplicate file names i.e. 275.raw and 275.jpg.

What is the normal naming convention your cell phone uses for files I.e. “filename.***” and are they really raw or JPEG?.  What happens if you duplicate one of the .RAW files to another location and rename to ****.jpg ? EDIT: or *****.dng

All the files in question appear to have the normal naming convention for the cell phone I used at the time.
Duplicating and moving and or renaming have no effect, still can't open the files.

I wonder if the files became corrupted when I changed cell phones and had the data transferred from the old phone to the new one?

That would seem to be a distinct possibility with the so called raw files some corrupted duplicates of the originals?

Moving and renaming of files outside of the LR interface is not recommended as you will loose the catalogue database association with your files, however I do not think that this could cause loss of original data or corrupt original files.

Are you sure they are not .acr files? A .acr file contains non-textual data that can be an AI-generated pixel-based mask and/or a LUT from ACR/LR.

All the files have the extension .raw
Is there something/someway I can check to see if they are .acr files?

The extension. Otherwise I don't think these are from an Adobe converter.

I can rename any file with a .raw extension.
