[digiKam-users] Updating raw file dates

[Alan H]

Thanks Maik. Just curious. Correct me if I’m wrong, but it seems apps change raw file date fields depending on modifications & last access. The blocks are already there and it is just the values that are changing. So, in a similar fashion, is really that dangerous to change to contents of other date fields, particularly date created (or whatever variation)? Aside from my own interest, would others (rhetorically asking) have a similar interest? In the change date/time feature could there be a toggle to include raw files?

Wait for digiKam-8.0.0, here it will be possible to enable ExifTool to write metadata.

It is safer to edit RAW files with ExifTool.


If you are keen to experiment and you make a backup of the database and your images,

you can download an automatically created Windows digiKam-8.0.0 version here:


https://binary-factory.kde.org/view/Windows%2064-bit/job/Digikam_Nightly_win64/ (*.exe file)


You have to do without HEIF support at the moment.

Select ExifTool in the setup in the digiKam program directory under /bin.
