AntiDir is basically the opposite of Dir.
For example, typing the command antidir *.exe will show the opposite of what dir *.exe will show you which is everything but the *.exe files.
By default, AntiDir also shows all hidden files (since this is the opposite of what dir does) and tells you whether it's a system file, read only and/or directory. Filter flags are provided to filter out files with these attributes.
		SYNTAX: AntiDir [file-filters] [filter-flags]
		FILTER FLAGS: filter out a type of file:
		/a	Archive files
		/r	Read-only files
		/h	Hidden files
		/s	System files
		/d	Directories
	
Check out this sample output with the following commands in my messy root directory:
| Command | files listed | Meaning of command line | 
|---|---|---|
| antidir foo | list all files except foo | |
| antidir /d | list all files except directories | |
| antidir /d *.bat *.sys *.txt | list all files except directories and those files matching *.bat, *.sys and *.txt | |
| antidir /d *.bat *.sys *.txt /h /s | list all files except directories, hidden and system files and those files matching *.bat, *.sys and *.txt | 
I find it useful for finding garbage files that accumulate in directories with a lot of files. I keep filtering out more and more files until I'm left with the remaining garbage files.
