how to use exiftool on multiple files in folder

I have not yet found an easy-to-use program that scans all of your photos and tells you which ones have geotags. For our purposes, there are many GPS-related Exif tags, but the most important ones store the GPS location information in latitude and longitude. This is a standard dating back to 1995 that defines a broad array of 'tags' that may be present in the metadata, including date, time, resolution, model of phone or camera, flash mode, f-stop, etc. The technical term for the way metadata is stored in JPG image files is Exif - Exchangeable image file format. Some picture display or editing programs may not be designed to show metadata at all, and others may not show the geotags. In order to see the metadata, you have to dig a little deeper. When you open a picture file on your computer, you normally only see the image. How can you find out if your existing photos contain location metadata?

So, now that you've learned how to avoid geotagging photos you take in the future, the next step is to deal with the photos you've already taken that may contain location metadata. How you can probably turn off the GPS unit in your phone or camera to prevent it from putting this information into future photos you take.

How dangerous it may be for you to post such photos online, or email them to anyone, or if your computer (or its backup) is compromised or stolen, because identity thieves, burglars, stalkers, pedophiles, and others may then exploit this location information to learn where and when you and (your family) spend your time.

How this information is stored as latitude and longitude, and how easy it is for anyone to translate those numbers into a street address.

How location metadata (also called 'geotags') stored in your photo files reveals where you were when you took each photo, along with the date and time and other information.

In last month's issue ('Dangerous Information Hidden in Your Digital Photos, Part 1' ) I wrote about how your GPS-equipped smartphone camera (or digital camera) may be storing your physical location in the 'metadata' of every photo you take. The hidden information in your photos that you probably aren't aware of
