Thank you for the feedback
My post 2024/09/16 contained errors, I understood through your response, and I corrected it.
We need to specify the folder in which the photos to be updated are stored.
I read the exiftool documentation ...
https://exiftool.org/exiftool_pod.html#csv-CSVFILE
"The -csvDelim option may be used to change the input/output field delimiter if something other than a comma is required."
ex -csvDelim ; or -csvDelim "\t" (Tab used as a delimiter) .
"Use "\t", "\n", "\r" and "\\" to represent TAB, LF, CR and '\' respectively"
I can also answer to my own questions
"Special feature: -csv+=CSVFILE may be used to add items to existing lists. This affects only list-type tags. "

If your captions contain commas, you can use another delimiter in the csv fileA problem with that is that many of the actual captions contain commas

"List-type tags are stored as simple strings in a CSV file, but the -sep option may be used to split them back into separate items when importing."For writing use, as these metadata are "list" type, i dont know how to write them with a csv file ...
"Special feature: -csv+=CSVFILE may be used to add items to existing lists. This affects only list-type tags. "
