Step 01:
Open up your command prompt by typing cmd in the run dialog box and hitting Enter.
Step 02:
Navigate to the directory which has the files and type the following command –
DIR /B /O:N > filename.txt
This will save all the filenames in the current directory to a text file. The text file will be saved in the same directory.
Step 03:
To save file names from any sub-directories in the current folder, just add /S like –
DIR /B /O:N /S > filename.txt
That’s all!
