If a folder name is given instead of a file, all files in the folder will be deleted, but the folder itself will not be removed.

Temporary Files
You should clear out TEMP files on a regular basis - this is best done at startup when no applications are running. To delete all files in all subfolders of C:\temp\ but leave the folder structure intact:

   DEL /F /S /Q %TEMP%

When clearing out the TEMP directory it is not generally worthwhile removing the subfolders too - they don't use much space and constantly deleting and recreating them can potentially increase fragmentation within the Master File Table.

Deleting a file will not prevent third party utilities from un-deleting it again, however you can turn any file into a zero-byte file to destroy the file allocation chain like this:

TYPE nul > C:\examples\MyFile.txt
DEL C:\examples\MyFile.txt

Undeletable Files

Files are sometimes created with the very long filenames or reserved names: CON, AUX, COM1, COM2, COM3, COM4, LPT1, LPT2, LPT3, PRN, NUL
To delete these use the syntax: DEL \\.\C:\somedir\LPT1
Alternatively SUBST a drive letter to the folder containing the file.

If a file (or folder) still appears to be 'undeletable' this is often caused by the indexing service.
Right click the file you need to delete, choose properties, advanced and untick "allow indexing" you will then be able to delete the file.
To cure the problem permanently - Control Panel, Add/Remove programs, Win Accessories, indexing service.

Delete Locked files (Typically IE temp files or the Offline cache)
This works on any version of NT, 2000 or XP

Close all applications
Open a command prompt
Click Start, and then Shut Down
Simultaneously press CTRL+SHIFT+ALT.
While you keep these keys pressed, click Cancel in the Shut Down Windows dialog box.
In the command prompt window, navigate to the cache location, and delete all files from the folder (DEL /s)
At the command prompt, type explorer, and then press ENTER.


Previous versions of Windows had the DELTREE command that deletes all files and sub folders.
DEL /s will delete all files
RD /s will remove all files and folders including the root folder.

:: Remove all files and subfolders but NOT the root folder

@echo off
pushd %1
del /q *.* 
for /f "Tokens=*" %%G in ('dir /B') do rd /s /q "%%G"

Normally DEL will display a list of the files deleted, if Command Extensions are disabled; it will instead display a list of any files it cannot find.

ERASE is a synonym for DEL
