You might have lots of files or photos stored in subdirectories (subfolders) and need to put them in a single directory (folder).
This is the magic spell you need to move all the files into that single directory:
Go to the root of the directories and type:
for /r %d in (*) do copy "%d" "..\NewFolder"
This will create a NewFolder above the root and put all the files in them.
