From Microsoft's TechNet - Dir:
If you use /a without specifying Attributes, dir displays the names of all files, including hidden and system files.
The following list describes each of the values that you can use for Attributes. Using a colon (:) is optional. Use any combination of these values, and do not separate the values with spaces.
h Hidden files
s System files
l Reparse points
r Read-only files
a Files ready for archiving
i Not content indexed files
- Prefix meaning "not"
Using following command you can list only directory (folder) names without any other information.
dir /B /AD
/A - allows us to specify the attributes that files need to have to be taken into account.
/B - option that means Bare format , i.e. a format that precisely not include header, size, summary, etc.
/D - for Directories
/AD - list only directories.
