What does the batch file do? The first line has the command cls. cls clears the screen window of any previous data. The next three lines start with REM for "remark." Lines begining with REM do not contain commands, but instructions or messages that will be ed for the user. The next two lines begin with the command deltree, deltree not only deletes files but directories and sub-directories. In this case the file is deleting the directory cookies and all the files inside. This directory is automatically rebuilt. The deltree has been passed the parameter /y, this informs the process to answer "YES" to any confirmation questions. Sometimes you type the DEL or one of its cousins, the system will ask "Are sure you want to do this?" setting /y answers these prompts without interupting the process. The pause command halts the process temporarily and shows the users a list of all the files being deleted. cls clears the screen again, another REM line tells the user that the files are deleted. The last line contains only :end and returns the process to the command prompt. This version was created to show the user everything that is taking place in the process. The version bellow does the same thing without showing the user any details.
cls
@echo off
deltree /y c:\windows\cookies\*.*
deltree /y c:\windows\tempor~1\*.*
cls
Without REM lines there are no comments. The @echo off command keeps the process from being "echoed" in the DOS window, and without the pause and :end lines, the process runs and exits without prompting the user. In a process this small it is okay to have it be invisible to the user. With more a complex process, more visual feedback is needed. In computing there is fine line between too much and too little information. When in doubt give the user the oportunity to see what is going on.
This version is a little more thurough, deletes alot of junk

"C:\windows\history\today" will rebuld itself if you delete it. It"s not a file, it"s a specially configured directory structure that DOS doesn"t see the same way that windows does. C:\windows\history\today doesn"t actually exist as DOS sees it. Go into the C:\windows\history directory and type DIR/A this will show you the hidden directories and how they are named.

One thing I do quite often is erase old floppy disks. I might have a stack of them and I don"t care what"s on them, but I want all the files gone including potential virii(everyone says "viruses" but "virii" is the proper term. Snob!). But I get tired of opening a DOS prompt and typing in the command to format the disk. So I wrote a one line batch file that does it for me. Save it as: "disk_wipe.bat"
Put a disk in the drive and double-click the .bat file icon.
