Hi Paul
Open File Explorer and navigate to that folder
In the address bar, just type cmd and hit Enter
That will open a Commend Prompt in that folder
Paste this into Command Prompt and hit Enter
dir /s/b > AAA.txt
Wait for that command to complete
That will have created a new text file in that folder - AAA.txt that will contain a listing of all files in that folder, including all sub-folders, which you can copy/paste into Word, Excel . . . etc.
If you just want to list files in a specific folder and not sub-folders, open a Command Prompt in that folder and run this command:
dir /b > AAA.txt
