First off, locate all the separate files. DEL is the delete command ...
@echo off
DEL C:\SELECTED FOLDER\FILENAME.EXT
DEL C:\ANOTHER SELECTED FOLDER\FILENAME.EXT
Where EXT is the file extension. To clean out a particular folder of all files use FILENAME.*
correction: To clean out a whole folder of files use *.*
*.* acts as a wildcard and will delete files of any name and any extension. Sorry about the edit.
Create a new Notepad file, rename the extension .BAT and edit the file with Notepad. You can add as many del lines as you wish. Case doesn't matter but path statements and file names are very important. You can place the batch file in your User Name folder, and when you open a CMD session the file will run from there. Copy the file, and paste a shortcut into your Start Menu Startup folder. The file should then run whenever you boot Windows.
PS: a good test might be to substitute DIR (directory or list) in place of the DEL command to make sure you have all paths and file names correct. Once you are sure of yourself use Find and Replace to switch out the DIR command for the DEL (delete) command.
I use a number of utility batch files myself, for backing up and syncing copies of files from my laptop to my desktop computer. Here's a batch file resource. I'm sure there are scores of others on the Web:
