How can I remove all the metadata from all the files inside a folder and its subfolders?
I've already tried several commands without any success. All of them were tied to a specific file extension and/or didn't go through all the subfolders inside.
You would use
exiftool -all:all= -r /path/to/files/
This command creates backup files. Add -overwrite_original
to suppress the creation of backup files.
You don't want to use wildcards to try to limit file selection (see Common Mistake #2). For that you would use the -ext
(extension) option.
Exiftool won't process any file that isn't on the writable file type list (see ExifTool FAQ #16), so files like AVI or MKV will be skipped.
You do not want to use this command on a RAW file type, such as NEF or CR2, as that will remove data that is required to render the image. See ExifTool FAQ #8.
