How long will it take to extract a csv of keywords from 40,000 photos in a hierarchy of directories and subdirectories?  THX.

There's really no way to answer that question.  It depends upon your computer. Where the files are located, on a SSD or on a nas.  And they all small 50x50 pixel emoji images or huge 100 meg+ tiff files.  Way too many variables and I doubt anyone has done any time trials on such an operation.

The only thing I could say is that it would probably take less time than it would to copy all those files.
"It didn't work" isn't helpful. What was the exact command used and the output.
Read FAQ #3 and use that cmd
Please use the Code button for exiftool output

Please include your OS/Exiftool version/filetype

Don't use the -csv option with such a large number of files.  Use JSON (-j) or XML (-X) instead.  Read the -csv documentation for details.

...where DIR is the name of a directory/folder containing the images.  On Mac/Linux/PowerShell, use single quotes (') instead of double quotes (") around arguments containing a dollar sign ($).
