Rename 1,000's of Files Based on MIME Type

Rename 1,000's of Files Based on MIME Type?

Ok, so I messed up and renamed every file in multiple folders ".jpg" ... DOH !!!

Renaming manually has ben slow and tedious.

I've looked at several exif commmand line examples but nothing matches what I am looking for. I found one but while researching all the MIME Types i lost link to script details.

What I need is a simple script that changes the extension of every file and sub-folder files based upon mime types

if MIMETYPE = "image/jpeg" rename FILENAME.EXTENSION

"image/jpeg"         = ".jpg"
"image/png"         = ".png"
"image/webp"         = ".webp"
"image/gif"         = ".gif"
"image/x-xcf"         = ".xcf"
"image/svg+xml"         = ".svg"
"image/bmp"         = ".bmp"

"text/plain"         = ".txt"
"text/html"         = ".html"

"application/postscript"   = ".eps"
"application/pdf"      = ".pdf"
"application/octet-stream"   = ".lnk"
"application/zip"      = ".zip"
"application/x-rar-compressed"   = ".rar"
"application/vnd.oasis.opendocument.graphics"   = ".odg"

"video/mp4"         = ".mp4"
"video/3gpp"         = ".3gp"
"video/x-matroska"      = ".mkv"
"video/x-msvideo"      = ".avi"


Thank you, in advance.

This should get you most of the way there:

exiftool "-filename<%f.$filetypeextension" -v DIR

I've added the -v so you will have a record of what happened.

This is entirely a problem with your PS script.  I don't know PS and don't recommend using it so I can't help here.
