List of writeable metadata ofr a specific filetype
« on: April 13, 2019, 08:26:36 AM »
Hello,

When I want to have a list of all writeable metadata, i use -listw tag.
But I would like to be more precise and have, for example, the list of writeable metadata for CR3 file (exif metadata are listed as writeable, for this is not the case for CR3 files).
Is there an option to have this information ?

Thank you for your help.

Olivier

The application doesn't return this type of information.  I've tried to provide a table with this information on the ExifTool home page, but this is really only a guideline since the actual answer is very complex and depends on the specifics of the file being written.

...where DIR is the name of a directory/folder containing the images.  On Mac/Linux, use single quotes (') instead of double quotes (") around arguments containing a dollar sign ($).

Hello Phil,

Thank you for your answer.
I will use the information from the ExifTool home page to manualy lock unwriteable fields according to the filetype I edit.

Nevertheless, ExifTool stays a powerfull tool i love to work with :)
