Protect unwritten metadata

[frlindla]

What is the default value here?

Have you considered clicking on the "Default" button? It restores all defaults.
If you don't close the dialog with OK, these changes are temporary.

I believe its "Yes", "No", "Yes".

Thank you. I tried the default button and it seems like the default is like you said.

I ask because I recently noticed a problem with one of our iphones. I imported photos into Imatch to a import folder. I added metadata and run the renamer. But then after a while I saw that some files had changed the date and time to wrong date and time. So I tried ctrl+shift+F5 and then reload metadata. Then it was right again. But then after a while it had changed again.

PS: When running the reload metadata command, Imatch tell me that I have the protect unwritten metadata on. So that`s the reason why I ask for this. Could this be the reason to the problems? But the problems seems to just be with one of our iphones, not the other.

I don't know about the source of the problems with these files.
Check How IMatch uses Date and Time Information and The Metadata Analyst in the IMatch help for some starting points.

This file has both an embedded XMP record and a sidecar file.
IMatch does not create XMP sidecar files for JPEG files. Do you have a RAW with the same name as the JPEG in the same folder? This would explain the extra XMP file.
Or do you use Mylio?
