Title: "Warning: No writable tags set from..."
Post by: Cobweb on November 11, 2020, 02:58:46 PM
Hi,

I wasn't sure whether to post here or in the The "exiftool" Application forum.  But I'm a newby, so I guess here's ok?

I have hundreds and hundreds of photos in a strange (to me) folder structure so I've simplified things by having exiftool create folders based on Years, then Months.  It shifted the whole lot in just over a day, awesome!  Saved me so much time and frustration.

I used the following command:
emm@i3:~$ exiftool '-Directory<CreateDate' -d /nfs/Photographs/%y/%m -r /nfs/Production/Photography/

However, some of the XMP sidecar files haven't gone over, they failed with the following message:

Warning: No writable tags set from /~/Bonus Day - 20 Feb/_DSC9251.NEF.xmp

Anyone shed any light? (in fairly simple terms).  Thanks in advance and sorry for the dumb question.  I'm using Linux Mint 20, just in case that helps :)

You'll get this warning for any file that doesn't contain a CreateDate tag.  If you want to use a fallback that always works, you can use FileModifyDate, ie)

exiftool '-Directory<FileModifyDate' '-Directory<CreateDate' -d /nfs/Photographs/%y/%m -r /nfs/Production/Photography/

... or use "exiftool -time:all -s FILE" to see what tags are available, and add all the ones you want (in reverse order of precedence) to the command.

Thank you so much!!  I've been scratching my head most of this evening trying to wrap my mind around the issue.

Thanks, dude, you're awsome!  :D
