You can use the following syntax in PowerShell to list all files in a directory to a CSV file:
ls | % Name > file_names.csv
This particular example will list out all file names in the current directory to a CSV file named file_names.csv.
Note that this syntax will list all file names with the extensions.
If you would instead like to list all file names without the extensions, you could use the following syntax instead:
ls | % Basename > file_names.csv
The following example shows how to use this syntax in practice.
