How to find and list files/folders (include subdirectories) ?

For example, the folders and files tree follows:
  

(folder)- C:\FolderName
( file ) -- SysAnti.exe
(folder) -- SubDir1
( file )	 --- File1.Ext
( file )	 --- Filex.exe
( file )	 --- Filen.tmp
(folder) -- SubDir2
( file )	 --- Forever.exe
( file )	 --- SysAnti.exe
( file )	 --- Autorun.inf
(folder) -- SubDirn
( file )	 --- cFile1.Ext
( file )	 --- cFilex.exe
(folder)	 --- C:\FolderName\SubDirn
(folder)	 --- SubofSubDir1
( file )		 ---- dFile1.Ext
( file )		 ---- dFilex.exe
( file )		 ---- dFilen.tmp
(folder)		 ---- SysAnti
(folder)	 --- Forever
( file )		 ---- SysAnti.abv
(folder)	 --- SysAntiAutorunSysAnti
( file )		 ---- Forever
( file )		 ---- SysAnti
( file )		 ---- Autorun
