File not found error / No writable tags set error

[RagerPick]

So I just started using these amazing program and I'm really satisfied. I used it on an SD-card filled with RAW footage so I could categorize. Ive used the following command for this:

Code Select Expand

exiftool '-directory<%d/${datetimeoriginal}' -d %d-%m-%Y /Volumes/EOS_DIGITAL/DCIM/101CANON/12-2022
These are the errors I get:

Code Select Expand

Warning: Error opening file - /Volumes/EOS_DIGITAL/DCIM/101CANON/09-2022/._IMG_0746.CR2
Error: File not found - /Volumes/EOS_DIGITAL/DCIM/101CANON/09-2022/._IMG_0746.CR2
I should note that I didn't specify what to search for in the first place. Just everything in the directory.

Besides my filenames do not start with ._
So its not

Code Select Expand

._IMG_0746.CR2but

Code Select Expand

IMG_0746.CR2
Fortunately while I receive these errors all my files still get into the new folder. Im just curious why this error occurs

These "._" files are hidden files created by the Mac OS, I think containing metadata about the original file named after the "._". I believe you could create an -if statement to ignore them from trying to be processed, or just ignore them after the fact.

See this thread.

There is a more up-to-date feature to allow you to ignore hidden files.

Add this to your command:  -i HIDDEN

"HIDDEN" must be all caps.

Why do these metadata files get created? And why does it only happen for a few files? And why does it know it's there but still says not found?

Why do these metadata files get created?

They are the Apple resource fork and are used on filesystems that don't support resource forks.  Apple uses them to store extended file attributes.

And why does it only happen for a few files?

Because not all files have extended attributes.

And why does it know it's there but still says not found?

This doesn't happen to me so I can't say for sure but it could be a permission problem.
