dir/b > files.txt
I guess it has to be done in PowerShell to preserve unicode signs.
Just found this great post, but needed it for sub directories as well:
DIR /B /S >somefile.txt
use:
Get-ChildItem -Recurse | Select-Object -ExpandProperty Fullname | Out-File Somefile.txt
or the short version:
ls | % fullname > somefile.txt
