dir files

# For finding file use dir followed by string matching file name or regex
# pattern and add "/s" for searching recursively in subfolders:
dir /s "regex_or_file_name"
# For finding file contained in a searched directory use "/b":
dir /b "directory_name"
# Use respectively '/a-d' or '/ad' for finding only files or only folders.
