Error Opening File Warning: Running EXIFTOOL on Synology NAS (Google Takeout)

[didums]

Hi,

I've stalked this forum, looking for some tips on how to get my setup right.

I'm running EXIFTOOL in the terminal on my Mac. The actual files are stored on my Synology NAS. When it executes, a small percentage of the metadata gets appended with no issues, something like 10% or so. The remaining images throw an error saying it can't access the file. The permissions look fine and I'm connected to the NAS as root/admin. Looking for any advice. Thanks in advance!

Here is the block I'm executing:


exiftool -r -d %s -tagsfromfile "%d/%F.json" "-GPSAltitude<GeoDataAltitude" "-GPSLatitude<GeoDataLatitude" "-GPSLatitudeRef<GeoDataLatitude" "-GPSLongitude<GeoDataLongitude" "-GPSLongitudeRef<GeoDataLongitude" "-Keywords<Tags" "-Subject<Tags" "-Caption-Abstract<Description" "-ImageDescription<Description" "-DateTimeOriginal<PhotoTakenTimeTimestamp" -ext "*" -overwrite_original -progress --ext json /Volumes/home


Here is the consistent error message:

Warning: Error opening file - /Volumes/home/ExtractTarSecondTry/Takeout-70/Google Photos/2018-04-21/G0050088.JPG.json

Here is the total output:
6018 image files updated
79239 image files unchanged
99 files weren't updated due to errors



I'm pressed on how fast this script runs and the options it has out of the 'box'. Looking forward to learning this one.

a small percentage of the metadata gets appended with no issues, something like 10% or so.

Only 99 files out of 85000 had this error (ie. a missing .json file).  The other ones didn't get updated because none of the source tags existed in the .json file.

Also, you don't need to run this command unless you made changes to the file on the Google website.  Google does not remove any metadata from the files.

I really need update that StackExchange answer to say this at the top in big, bold letters.

Thanks, for the feedback.

I actually did read the StackExchange piece that outlined that Google doesn't remove any metadata. I think it's good to reinforce the comment, just so many JSON files to digest to validate (fear of missing data). I'd also call out that with Google's new photos policy, these questions will start to pop-up more and more as consumers find alternative solutions to paying Google more $$.

Thanks, both for the quick reply.
