Faststone Image Viewer DNG renaming problems


I was today bulk renaming a bunch of files with Faststone Image Viewer 7.7 (Windows 10).

These files were "Linear DNGs" created using DxO PhotoLab 5 in February 2022.

I first noticed the problem with some DNGs I took in October 2022. The date (for example) was 22/10/21 (DD/MM/YY).

So, the original file name was " IMG_2567 ". The new name should have been " 20211021_IMG_2567 ". Instead the name was " 20220223_IMG_2567 ".

The date on the file names is the date of DxO processing, not the date of actually taking the photo, which is NOT what I want. The taken date is still stored within the file.

I need to know:

  1. How can I rename the affected files, back to their original state
  2. Why is Faststone Image Viewer doing this?


Thanks, Dunlin.
