Deleting all files and directories from desktop except .lnk - windows

Question

Im trying to write a script for keep clear my desktop. I want to delete all files and directories except the shortcuts.I use Windows 10. My batch code is the following:
#echo off
COLOR 0E
cd "C:/Users/DA/Desktop"
FORFILES /S /C "if #ext!=lnk del /F /Q /S"
rd /S /Q "."
pause
exit
Maybe it is a dumb error, but Im a newbie in Windows command line. Thanks in advance.

Answer 1

There are several issues in your code:
You must precede the command line after the /C switch of forfiles with cmd /C, because you are using internal console commands (if, del). If you omit cmd /C, forfiles tries to find a program file named if, which does not exist.
There is no comparison operator != for the if statement. You mean not equal, so you need to state if not <expression1>==<expression2> instead.
The #ext variable expands to the file extension enclosed in quotation marks, so you need to state them around lnk also. Since the "" are in the quoted command line behind forfiles /C, you need to escape them like \" in order to establish literal " characters.
You forgot to specify what to delete at the del command.
The switches /S of forfiles and also del mean to process also items in sub-directories, but I assume you do not want that, because you want to clean up your Desktop directory.
There is the rd command, so I assume you want to remove any directories from the Desktop either. However, rd /S /Q "." tries to remove the entire Desktop directory (which will fail as your batch file changes to that directory by cd). I would put the rd command into the forfiles command line as well, because there is the possibility to check whether or not the currently iterated item is a file or a directory (forfiles features the #isdir variable for that purpose).
The cd command works only if you are running the batch file from the same drive where the Desktop directory is located (unless you provide the /D switch). I would go for the pushd command, which changes to the Desktop directory temporarily, until a popd command is there.
Instead of hard-coding the location of the Desktop directory, I would use the built-in environment variable %USERPROFILE%, which points to the user profile directory of the currently logged on user, where the Desktop directory is located in.
The exit command without the /B switch does not only end the batch file, it also terminates the command interpreter instance the batch file is running in. This does not matter when you run the batch file by double-clicking, but it does matter when you execute it within command prompt.
Here is the corrected and improved code:
#echo off
title Clean Up Desktop & rem // (this is the window title, just for fun)
color 0E
pushd "%USERPROFILE%\Desktop" || exit /B 1 & rem // (the command after `||` runs if `pushd` fails, when the dir. is not found)
rem /* Here you can see how to distinguish between files and directories;
rem files are deleted with `del`, directories are removed with `rd`.
rem The upper-case `ECHO`s are there for testing purposes only;
rem remove them as soon as you actually want to delete any items: */
forfiles /C "cmd /C if #isdir==FALSE (if /I not #ext==\"lnk\" ECHO del /F /Q #relpath) else ECHO rd /S /Q #relpath"
pause
popd & rem // (this restores the previous working directory)
exit /B & rem // (this quits the batch file only; not necessary at the end of the script)

You can try something like that :
#echo off
COLOR 0E
CD /D "%userprofile%\Desktop"
Rem To delete folders
for /f "delims=" %%a in ('Dir /b /AD ^| find /v "lnk"') do echo rd /S /Q "%%a"
pause
Rem To Delete files
for /f "delims=" %%a in ('Dir /b ^| find /v "lnk"') do echo del /F /Q /S "%%a"
pause
exit
NB: When your execution is OK, just get rid of echo command

Answer 3

You can use the for and if commands to accomplish this:
#echo off
COLOR 0E
cd C:/Users/DA/Desktop
for /d %x in (*) do #rd /s /q "%x"
for %i in (*) do if not %i == *.lnk del "%i"
pause
Pretty simple and works great.
Make sure that %i and %x are in "".
