Description sourcemaker 2025-10-07 21:31:09 UTC 
I have thousands of images, but they use different date formats in their file names.

IMG_yyyyMMdd_hhmmss
IMG_yyyyMMdd_hhmmss_zzz
yyyyMMdd_hhmmss
yyyy_COUNTER

Therefore, I am looking for a way to ensure that all images use the same date format in the file name.

When I use [meta:Exif.Photo.DateTimeOriginal], I cannot change the date format.
The [date] option allows me to change it, but uses the file system's modification date as a fallback if no Exif metadata is available. This makes it unusable.

Feature request:
If possible, rename all images using the option [meta:Exif.Photo.DateTimeOriginal] to IMG_yyyyMMdd_hhmmss_zzz. Otherwise, keep the file name unchanged.

Here's an example of your possible renaming string:

IMG_[meta:Exif.Photo.DateTimeOriginal]{dateformat:yyyyMMdd_hhmmss_zzz}

or:

IMG_[file]{dateformat:yyyyMMdd_hhmmss_zzz}
