Offset for FileNumber

[pepete]

Hello together,

I am searching for a possibility to add an offset to the filenumber to rename my files but I could not find a way to do this.

Thank you and best regards,

Peter

Hi Peter,

If you are talking about the Canon FileNumber, it is a Composite tag derived from DirectoryIndex and FileIndex.  To add an offset to FileIndex, use this command:

exiftool -fileindex+=21 image.jpg

Hey Phil,

thank you for your help. In my case it is a Nikon D5100, but this helps me. I can now just update the filenumber and then rename the files with the updated filenumber!

Thank you,

Peter
