Deleting File in Batch?

Question

how do i make it so my batch file deletes a specific file without asking user permission?

Answer 1

By default, the DOS "del" command does not ask for user permission if you're deleting files without using global wildcards.

You can test this by changing into your temp directory and creating a file to delete. Let's call that "test.txt". In your batch file, a simple line of "del \temp\test.txt" will delete the file without asking for permission.

You can test deleting multiple files by creating test1.txt, test2.txt, test3.txt, etc. Then, in your batch file, a line of "del \temp\test.*" will delete all the files without asking for permission.

A third test, create some files in your temp dir and try a line of "del \temp\*.*" will ask "Are you sure (Y/N)?" because you're using a global wildcard. To get around that you would modify the line to read "del \temp\*.* /q" to delete files "quietly", meaning without asking for permission.

Answer 3

create a text file named del.dat, right click and choose edit
paste the following code,

IF EXIST "C:\file.txt" (
DEL /F "C:\file.txt"
) ELSE (

)

this will not prompt you, but if you dont have permission(system file, or locked file) it will not delete (you will have to do a brute force program to kill a locked file).
