I have a situation where I am copying thousands of photos of different filetypes into new folders on a new drive. Photos in their current state are unorganized and need to be structured better. I will copy the picturefiles manualy. My concern is that after I am done I might miss some pictures in my newly organised drive. I cannot simply compare the two drives (or folders) because their subfolders are not mirrors of themselves.
Essentialy I want to tell my computer:
"Check that every individual file (not checking folders) in F:\oldpictures
has excact copy in somewhere in D:\newpictures
. If file (picture) is missing notify user."
What would be the easiest way to check this? Is there a way built into windows 10?
