windows - How to get attributes of a file using batch file

Question

I am trying to make a batch file to delete malicious files from pendrive. I know that these malicious files uses hidden,read only and system attributes mainly to hide itself from users. Currently i am deleting these files using cmd by removing malicious files attributes then deleting it. Now I am thinking to make a small batch file which can be used to remove these files just by entering the drive letter.

I have found this code in a website to find attributes of a file. But after entering the name of the file the batch file just exits without showing any results.

    @echo off
setlocal enabledelayedexpansion
color 0a
title Find Attributes in Files

:start
set /p atname=Name of the file:
if not exist %atname% (
cls
echo No file of that name exists!
echo.
echo Press any key to go back
pause>nul
goto start
)
for /f %%i in (%atname%) do set attribs=%%~ai
set attrib1=!attribs:~0,1!
set attrib2=!attribs:~1,1!
set attrib3=!attribs:~2,1!
set attrib4=!attribs:~3,1!
set attrib5=!attribs:~4,1!
set attrib6=!attribs:~5,1!
set attrib7=!attribs:~6,1!
set attrib8=!attribs:~7,1!
set attrib9=!attribs:~8,1!
cls
if %attrib1% equ d echo Directory
if %attrib2% equ r echo Read Only
if %attrib3% equ a echo Archived
if %attrib4% equ h echo Hidden
if %attrib5% equ s echo System File
if %attrib6% equ c echo Compressed File
if %attrib7% equ o echo Offline File
if %attrib8% equ t echo Temporary File
if %attrib9% equ l echo Reparse point
echo.
echo.
echo Press any key to go back
pause>nul
goto start

can you tell me why this batch file is exiting without showing any results. Or can you give any better batch script for getting attributes of a file.

EDIT

I was able to work the above code only for a single file. As my purpose of my batch file is to remove malicious files by entering the drive letter. How can i use it to find what kind of attributes files are using in a particular drive.

For example: In cmd we can use this command to find the file attributes of a given drive

attrib *.*

Advance thanks for your help

You're using a for /f loop here, which isn't necessary (and may yield undesired results if the filename contains spaces). Change this:

for /f %%i in (%atname%) do set attribs=%%~ai

into this:

for %%i in ("%atname%") do set attribs=%%~ai
