I would normally open the parent folder and search for
* in order to select all of the files in subfolders, but in this instance, I have over 1,000,000 files that I need to sort through, so my explorer often crashes when trying to copy that many files through the GUI. I am not sure how much more effective this will be through the command prompt or a batch file, but it is worth a try, I suppose.
What I need to do is make it so that
|parent | |123 | | 123abc.png | |456 | | 456def.png | |789 | | 789ghi.png
|parent | 123abc.png | 456def.png | 789ghi.png
Yes, my actual file structure has the first 3 characters of the file name given to the folder name, if that can help at all in sorting these.
