In my current image download folder, I see a bunch of acr files, which still bear their original import file naming, along with my NEF files and their corresponding xmp files. Most are small- 9-26k, but some are quite large, several MB in size.
As I understand it, the acr files have something to do with masking, but what I want to know is when I renamed my NEF files, and the corresponding XMP files got renamed, should the acr files have gotten renamed as well? I do not see any acr files that have been renamed to match the NEF/xmp files.
If I still have those acr files in the folder, but they still have the original file import names, does that mean that when I deleted some raw files in Lightroom, it did not remove these acr files, and they are now safe to discard now?
Photoshop 25.11.0, Lightroom Classic 13.4, Camera Raw 16.4., macOS 14.6.1
