Use ExifTool’s recursive option, -r, and point it at the top-level folder instead of using *.jpg.

Example:

exiftool -csv -CreateDate -Keywords -r -ext jpg "C:\path\to\top\folder" > data.csv

What this does:

• -r scans all subfolders recursively
• -ext jpg limits processing to JPEG files
• -csv writes the selected tags in CSV format
• -CreateDate -Keywords selects the metadata fields you want

Your original *.jpg wildcard only matches files in the current directory, which is why subfolders were skipped.

If needed, use the full path to the top folder to avoid ambiguity. Quoting the path is helpful when folder names contain spaces.
